 Leila Haegel</a>\nby Leïla Haegel (University of Paris) as part of CMO-De
 tection and Analysis of Gravitational Waves in the era of Multi-Messenger 
 Astronomy\n\n\nAbstract\nThe direct detection of gravitational waves opene
 d an unprecedented channel to probe fundamental physics. Proposed extensio
 ns of our current theories predict a dispersion of the gravitational waves
  during their propagation\, distorting the signals observed by ground-base
 d interferometers compared to their predictions from general relativity.  
 In this talk\, I present several analysis probing different alternative th
 eories of gravitation. Using the multimessenger events consisting of gravi
 tational waves and their electromagnetic counterpart\, extra dimensions an
 d scalar-tensor theories are constrained from the comparison of the lumino
 sity distance inferred independently from both signals. Relying only on gr
 avitational wave signals\, a large class of proposed theories (e.g. massiv
 e gravity) predict a frequency-dependent dispersion of the gravitational w
 aves breaking local CPT and/or Lorentz symmetry. Constraints on the corres
 ponding effective field theories coefficients are obtained from the analys
 is of 31 events from the second LIGO-Virgo detections catalog.\n

  Michael Coughlin (University of Minnesota) as part of CMO-Detection and A
 nalysis of Gravitational Waves in the era of Multi-Messenger Astronomy\n\n
 \nAbstract\nWe present a novel paradigm for the deployment of computing in
 frastructure for the low-latency analyses of gravitational wave (GW) data.
  Here\, we specifically discuss two deep-learning algorithms\, 'DeepClean'
  and 'BBHNet'\, which are used for GW data denoising and compact binary so
 urce identification respectively. Using “replayed” streams of the GW d
 ata of LIGO Hanford and Livingston from their third observing run\, we dem
 onstrate the subtraction of stationary and non-stationary noise sources fo
 llowed by identification of candidates for the astrophysical transient det
 ections at low latency. Depending on the computing platform used\, we show
  that it is possible to achieve these at latencies of ~ a few hundreds of 
 milliseconds to a few seconds. Real-time delivery of gravitational-wave al
 erts is important for enabling rapid multi-messenger follow-up\, especiall
 y to capture short-lived electromagnetic counterparts. Additionally\, our 
 implementation offers seamless incorporation of hardware accelerators and 
 enables the use of as-a-service computing\, which would be capable of meet
 ing the future needs of gravitational-wave data analysis.\n

 part of CMO-Detection and Analysis of Gravitational Waves in the era of Mu
 lti-Messenger Astronomy\n\n\nAbstract\nGravitational waves have opened a n
 ew window on the Universe and paved the way to multimessenger astronomy. A
 dvanced LIGO and Advanced Virgo interferometers are probing an increasingl
 y larger volume of space\, discovering more and more signals produced by t
 he coalescence of compact binary systems. Characterizing these detectors a
 nd their noise is crucial to optimize the sensitivity. In particular\, gli
 tches are transient noise events impacting the data quality\, and their de
 tection and classification is very important to improve the performance of
  the interferometers. Deep learning techniques are a promising approach to
  recognize and classify glitches and to study noise in general. We will pr
 esent how machine learning can help in investigating the time-frequency ev
 olution of glitches and thus contribute to the low-latency characterizatio
 n of gravitational wave detectors.\n

 lysis of Gravitational Waves in the era of Multi-Messenger Astronomy\n\n\n
 Abstract\nInstrumental and environmental transient noise bursts in gravita
 tional-wave detectors\, or glitches\, may impair astrophysical observation
 s by adversely affecting the sky localization and the parameter estimation
  of gravitational-wave signals. Denoising of detector data is especially r
 elevant during low-latency operations because electromagnetic follow-up of
  candidate detections requires accurate\, rapid sky localization and infer
 ence of astrophysical sources. NNETFIX is a machine learning-based algorit
 hm designed to remove glitches detected in coincidence with transient grav
 itational-wave signals. NNETFIX uses artificial neural networks to estimat
 e the portion of the data lost due to the presence of the glitch\, which a
 llows the recalculation of the sky localization of the astrophysical signa
 l. The sky localization of the denoised signal may be significantly more a
 ccurate than the sky localization obtained from the original data or by ex
 cising the portion of the data impacted by the glitch. We test NNETFIX in 
 simulated scenarios of binary black hole coalescence signals and discuss t
 he potential for its use in future low-latency LIGO-Virgo-KAGRA searches.\

 Abstract\nThe interplay between dark matter and black holes remains largel

 ong as these are primordial\, i.e. they are formed in the very early unive
 rse. Dark matter can also accumulate *around* black holes\, be them astrop
 hysical or primordial\, and modify the rich phenomenology  exhibited by th
 ese objects. After a brief overview of the status of dark matter searches\
 ,  I will discuss the prospects for detecting primordial black holes\, or 
 robustly ruling them  out as dark matter candidates. I will then discuss t
 he prospects for characterizing and identifying dark matter using gravitat
 ional waves\, covering a wide range of dark matter candidate types and sig

 O-Detection and Analysis of Gravitational Waves in the era of Multi-Messen
 ger Astronomy\n\n\nAbstract\nDistinguishing black hole – neutron star bi
 naries from binary black holes mergers for high mass ratios could be chall
 enging because the neutron star coalesces with the black hole without expe
 riencing significant disruption. To investigate the transition of the beha
 vior of a mixed binary merger into one like a black hole binary\, we prese
 nt results from a series of merger simulations for different mass ratios. 
 We show how the degree of disruption of the neutron star impacts the inspi
 ral and merger dynamics\, the properties of the final black hole\, the acc
 retion disk formed from the circularization of the tidal debris\, the grav
 itational waves\, and the strain spectrum and mismatches. The simulations 
 use initial data constructed with a method that generalizes the Bowen-York
  initial data for black hole punctures to the case of neutron stars.\n

  Using Convolutional Neural Networks</a>\nby Vasileios Skliris (Cardiff Un

  the era of Multi-Messenger Astronomy\n\n\nAbstract\nConvolutional Neural 
 Networks (CNNs) have demonstrated potential for the real-time analysis of 
 data from gravitational-wave detector networks for the specific case of si
 gnals from coalescing compact-object binaries such as black-hole binaries.
  Unfortunately\, training these CNNs requires a precise model of the targe
 t signal\; they are therefore not applicable to a wide class of potential 
 gravitational-wave sources\, such as core-collapse supernovae and long gam
 ma-ray bursts\, where unknown physics or computational limitations prevent
  the development of comprehensive signal models. We demonstrate for the fi
 rst time a CNN with the ability to detect generic signals -- those without
  a precise model -- with sensitivity across a wide parameter space. Our CN
 N has a novel structure that uses not only the network strain data but als
 o the Pearson cross-correlation between detectors to distinguish correlate
 d gravitational-wave signals from uncorrelated noise transients. We demons
 trate the efficacy of our CNN using data from the second LIGO-Virgo observ
 ing run. We show that it has sensitivity approaching that of the "gold-sta
 ndard'' unmodeled transient searches currently used by LIGO-Virgo\, at ext
 remely low (order of 1 second) latency and using only a fraction of the co
 mputing power required by existing searches\, allowing our models the poss
 ibility of true real-time detection of gravitational-wave transients assoc

 istic astrophysical phenomena.\n

  supernova simulations of massive pop III progenitor stars at the transiti
 on to the pulsational pair instability regime. We simulate two progenitor 
 models with initial masses of 85 and 100 solar masses with multiple equati
 ons of state. The 85 solar mass progenitor experiences a pair instability 
 pulse coincident with core collapse\, whereas the 100 solar mass progenito
 r has already gone through a sequence of four pulses 1\,500 years before c
 ollapse in which it ejected its hydrogen and helium envelope. The 85 solar
  mass models experience shock revival and then delayed collapse to a black
  hole due to ongoing accretion. We show the models have strong gravitation

  are essential for providing waveforms that can assist the detection and i

 An emerging theme in core-collapse supernova modelling is the wider import
 ance of magnetic fields. While magnetorotational explosions have long been
  investigated as a scenario for rare hypernova explosions\, recent simulat
 ions suggest that magnetic fields may play an important role in normal exp
 losions as well. To better understand the role of magnetic fields both in 
 normal and hyperenergetic explosions\, it is also imperative to revisit th
 e interplay of convection\, magnetic fields and rotation during the pre-su
 pernova evolution of massive stars. I will discuss progress on 3D magnetoh
 ydrodynamic simulations of supernovae and their progenitors\, possible imp

 \n\n\nAbstract\nThe search of gravitational waves (GW) from core-collapse 
 supernovae (CCSNe) relies on detection algorithms such as coherent WaveBur
 st (cWB). False alarm rates and statistical significance might be affected
  by blip and glitch noises embedded in the strain data\, which survive rej
 ection tests. It is of interest then to detect and discard surviving noise
  events. This work presents the use of supervised machine learning (ML) me
 thods\, in specific\, Linear Discriminant Analysis and Support Vector Mach
 ines\, to recognize between noise and signal events using a set of reconst
 ruction parameters from cWB. We tested this ML follow-up method using stra
 in data from the O3a run of advanced LIGO\, and CCSNe GW signals extracted
  from 3D simulations. The ML model is learned using a dataset of noise and
  signal events extracted from a given on-source window\, and then it is us
 ed to identify and discard noise events in cWB analyses in different on-so
 urce windows. Noise and signal reduction levels were assessed in single de
 tector networks (L1 and H1) and two detector networks (L1H1). The results 
 showed an effective enhancement of the statistical significance of cWB-bas
 ed searches of GWs from CCSNe.\n
