Title: Gravitational waves: from black holes to the cosmos Gravitational waves reveal the universe through an entirely unique spectrum, complementary to electromagnetic and neutrino observations. Although the field is young, it has already revolutionized our understanding of black holes and neutron stars, with implications for gravity, stellar and galactic astrophysics, nuclear physics and cosmology. In … Continue reading "CRA Seminar – Maximiliano Isi – Flatiron Inst. NYC"

Title: Galaxy Evolution and the Cosmic Baryon Cycle in 3D Abstract Galaxies are intricately linked to the gas in and around them, making the characterization of gas flows essential for directly constraining star formation, gas flow rates, and feedback processes, as well as for testing modern theories of galaxy evolution. The recent deployment of highly … Continue reading "CRA Seminar – Yuguang Chen UC-Davis"

Title: The anti-aligned spin of GW191109: Glitch Mitigation and its Implications  Abstract: One of the most interesting events in the third LVK observing run was GW191109, which was found to have spins which were confidently anti-aligned with the orbital angular momentum - one of only two such cases which has been released - and high … Continue reading "CRA Seminar – Rhiannon Udall, Caltech"

 Title: Probing neutron star physics via multimessenger astronomy Abstract: In this talk I will review recent work that allowed us to obtain a better understanding of the neutron star equation of state and neutron star properties by use of multimessenger observations of (binary) neutron stars. I will also discuss recent and current efforts of modeling binary neutron … Continue reading "CRA Seminar – Vasilis Paschalidis, U. of Arizona [Host Tamara Bogdanovic]"

Title: Dust Scattering Halo of black hole binary 4U 1630-47 Observed with Chandra and APEX: Using mm and X-ray Imaging to Constrain Source and Molecular Cloud Distances Abstract: Dust scattering halos have been utilized to study spectral variations during eclipses, physical properties and distribution of dust grains in the interstellar medium (ISM), X-ray extinction, and … Continue reading "CRA Seminar – Emrah Kalemci [Host Matthew Liska]"
