Description
The advent of gravitational wave astronomy has heralded a new era in multi-messenger astrophysics, offering unprecedented insights into the cosmos through the synergistic analysis of gravitational waves, electromagnetic signals, and other cosmic messengers. This collaborative approach has not only enhanced our understanding of some of the universe's most enigmatic phenomena, such as binary neutron star collisions, but has also paved new pathways for exploring the fundamental laws of physics and the nature of the Universe itself.
This session welcomes presentations that utilize joint observations with gravitational waves and other astronomical messengers as probes into fundamental physics, cosmology, and astrophysics. Furthermore, we invite contributors to share works that offer software tools designed for simulating, analyzing, or aiding in the joint observation of gravitational waves and other messengers.
The huge luminosity, the redshift distribution extending at least up to z~10 and the association with the explosive death of very massive stars make long GRBs extremely powerful probes for investigating the early Universe (pop-III stars, cosmic re-ionization, SFR and metallicity evolution up to the “cosmic dawn”) and measuring cosmological parameters. At the same time, as demonstrated by the...
TianQin, a space-based gravitational wave (GW) detector scheduled for launch in the mid-2030s, promises groundbreaking insights into the Universe. Operating in the milli-Hertz band, TianQin can detect a diverse array of sources, including double white dwarfs (DWDs), massive black hole binaries (MBHBs), stellar-mass black hole binaries (SBHBs), extreme mass ratio inspirals (EMRIs), and the...
Continuous gravitational wave (CW) searches targeted at known pulsars utilize electromagnetic observations of the sources to infer the phase-evolution parameters of the gravitational wave signal. We present a new method to perform Bayesian estimation of the amplitude parameters of a CW signal. The method leverages the well-established CW detection statistic, the F-statistic, and modern...
The landmark detection of a gravitational wave (GW) from the Binary Neutron Star Merger (BNS) GW170817 and its electromagnetic counterparts allowed us to study the Universe in a totally new way. Among the several discoveries made possible by GW170817, we can find the tightest constraints on the speed of gravity and the first measure of the Hubble constant (H0). Both these two measures were...
Gravitational waves (GWs) from compact binary coalescences are standard sirens that can probe the cosmic expansion history of the late-time Universe once the binary chirp mass-redshift degeneracy is broken. Methods for injecting redshift information into the inference process range from the direct detection of electromagnetic counterparts ("bright sirens") to the use of statistical properties...
The standard sirens in the gravitational wave (GW) astronomy provide us with a direct measure of the cosmological distances independent of the cosmic distance ladder. When accompanied by an electromagnetic counterpart, it can also provide a redshift measurement, thus offering a new avenue to probe the cosmic expansion rate today, also known as the Hubble constant H0. However, the majority of...

Ever since the observation of GW170817 provided evidence for binary neutron star mergers as sources of gravitational waves and other transient emissions such as short gamma-ray
bursts, the development of electromagnetically informed gravitational-wave analysis pipelines
has gained relevance in the astrophysics community [2, 1, 3, 4]. In this talk, I will illustrate...
The GW-Universe Toolbox is a software package designed to simulate observations of various types of gravitational wave (GW) source populations using a wide range of GW detectors, including ground-based and space-based laser interferometers, as well as pulsar timing arrays. In its recent development, the GW-Universe Toolbox has been upgraded to enable the simulation of joint observations of...
