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, … 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 … 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 … 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 … 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]"

Title: Thermonuclear X-ray Bursts in the NICER Era Abstract: Thermonuclear X-ray bursts are sudden flashes observed from some low-mass X-ray binaries. Time-resolved spectral analysis and long-term observations have revealed that they occur due to the unstable thermonuclear burning of the accreted matter on the surface of the neutron star. They typically last a few tens of … Continue reading "CRA Seminar – Tolga Guver [Host Matthew Liska]"

Title: The Growth and Evolution of SMBHs via Galaxy Mergers Abstract: After decades of SMBH observations, the connection between AGN triggering and galaxy mergers remains incomplete, although AGN are likely key players in the evolution of massive galaxies. Theoretically, there are many reasons to expect a link between galaxy mergers and the accretion of material … Continue reading "CRA Seminar – Adi Foord, U. of Maryland Baltimore County [Host Tamara Bogdanovic]"

Title: The Origin of Supermassive Black Holes from Pop III.1 Seeds Abstract: The origin of supermassive black holes (SMBHs) is a key open question for contemporary astrophysics and cosmology. Here we discuss the predictions of a model of SMBH formation from Pop III.1 protostars, i.e., metal-free stars forming in locally isolated dark matter minihalos, where dark … Continue reading "Special CRA Seminar – Jonathan C. Tan [Host John Wise]"
