Xavier Rodriguez

11/15/22, 11:00 AM

Evidence is pointing more and more clearly to blazars and other active galaxies as significant multi-messenger sources.
In this talk I summarize some of the latest developments in the modeling of cosmic-ray interactions in blazars and how these models can explain recent associations between IceCube events and individual sources. I also discuss the predicted flare signatures across the...

60. Teieresias Radiative Transfer: Consistently modelling the Kilonova Afterglow with Relativistic Hydrodynamics.

Ethan van Woerkom

11/15/22, 11:30 AM

The kilonova afterglow is the final phase of the electromagnetic counterpart to a BNS/NSBH merger, and it is the only predicted counterpart of GW170817, which has not been observed yet. The kilonova afterglow lightcurve is dependent on the mass, velocity and angular distributions of the ejecta, and thus represents an opportunity to independently constrain these properties. We present Teiresias...

62. Multi-Messenger studies: From ideas to realization

Jakob Nordin

11/15/22, 12:00 PM

I will use the recently observed association between extragalactic neutrinos and tidal disruption events as a starting point for an exploration of the tools needed to go from a scientific hypothesis to an active, high throughput time-domain program. I will introduce some of the concepts built into the AMPEL platform which were designed to make this possible.

The Deeper Wider Fast Programme (DWF) aims to discover and rapidly follow up the fastest bursts in the Universe (those lasting only milliseconds to hours). For this, we execute a main strategy comprised of coordinated international multi-facility, all-wavelength, and multi-messenger telescope observing runs to detect and follow up fast...

Lorenzo Natalucci

11/15/22, 3:00 PM

The Gamma-Ray International Transient Array observatory (GRINTA) is a fast class mission designed to be a major breakthrough in the next decade (>2030) time domain astronomy, in particular for the multi-messenger domain. Transient signals from sources of gamma-ray bursts, gravitational waves and high energy neutrinos are known to produce hard X-rays that can be detected by an instrument with...

61. General Coordinates Network (GCN): NASA’s Next Generation Time-Domain and Multimessenger Astronomy Alert System

Leo Singer

11/15/22, 4:00 PM

The Gamma-ray Coordinates Network (GCN) is a public collaboration platform run by NASA for the astronomy research community to share alerts and rapid communications about high-energy, multimessenger, and transient phenomena. Over the past 30 years, GCN has helped enable many seminal advances by disseminating observations, quantitative near-term predictions, requests for follow-up observations,...

Sylvia Zhu (DESY)

11/15/22, 5:00 PM

In the last few years, very-high-energy (>100 GeV) emission from gamma-ray bursts (GRBs) has been detected for the first time, allowing us to build a multiwavelength picture of GRBs that extends all the way up to TeV energies. Now that we’ve detected a few GRBs, the question becomes: What’s next? In this talk, I will describe the GRB programs of the current generation of air Cherenkov...

The study of flaring astrophysical events in the multi-messenger approach requires instantaneous follow-up observations to better understand the nature of these events through complementary observational data. We present Astro-COLIBRI as a meta platform for the patchwork of different specific tools in the real-time multi-messenger...
