CRA Seminar by Jacob Lange (RIT)

Web: https://ccrg.rit.edu/user/jacob.lange Title: RIFT'ing the Waves: An algorithm to perform Rapid parameter inference on gavitational wave sources via Iterative FiTing Abstract: As the gravitational wave (GW) observatories get more sensitive, the number of confident detection will grow exponentially. Conventional parameter estimation (PE) algorithms have to use specifically-tuned settings with fast waveform models to estimation parameters … Continue reading "CRA Seminar by Jacob Lange (RIT)"

CRA seminar by Dr. Lionel London (MIT)

Web: "https://space.mit.edu/people/london-lionel-t" Title: On the gravitational wave multipole moments of systems with angular momentum Abstract: Since Einstein's quadrupole formalism, multipolar analysis has played a central role in gravitational wave theory. In particular, gravitational waves from compact sources are ubiquitously represented using spin weighted spherical harmonic multipoles. But there is good reason to expect that a … Continue reading "CRA seminar by Dr. Lionel London (MIT)"

CRA seminar by Dr. Sanjay Reddy (University of Washington)

Web:https://phys.washington.edu/people/sanjay-reddy Title: Neutron stars in the multi-messenger era Abstract: About 50 years after their discovery, neutron stars are poised to take center stage in this era of multi-messenger astrophysics.  I will highlight advances in theory and key observations including GW170817 that have provided fundamental new insights about neutron star properties and their central role in … Continue reading "CRA seminar by Dr. Sanjay Reddy (University of Washington)"

CRA Seminar by Dr. Juliette Becker (Caltech)

Web: https://sites.google.com/view/jcbecker/ Title: Forming hot Jupiters: observational constraints on gas giant formation and migration Abstract: The three commonly considered pathways for hot Jupiter formation are in situ formation, runaway accretion in the outer disk followed by disk migration, and tidal migration (occurring after the disk has dissipated). None of these explains the entire observed sample … Continue reading "CRA Seminar by Dr. Juliette Becker (Caltech)"

CRA Seminar by Prof. Marianne Vestergaard (Niels Bohr Institute, Univ. of Copenhagen)

Web: https://dark.nbi.ku.dk/people/marianne/ Title: Determining black hole masses of active galactic nuclei across cosmic time Abstract: Observations show that supermassive black holes can affect their environment through outflows and other feedback processes. In order to establish the exact role that supermassive black holes play for galaxy evolution, we need to determine accurately the mass of the … Continue reading "CRA Seminar by Prof. Marianne Vestergaard (Niels Bohr Institute, Univ. of Copenhagen)"

CRA Seminar by Aycin Aykutalp (Los Alamos National Laboratory)

Title: Long- and Short-Distance Relationships with Massive Black Holes Abstract : In the last decade, growth of supermassive black holes in the centers of galaxies and their role in shaping the evolution of galaxies and their star formation histories has become a central topic in cosmology. However, the underlying physics of how a black hole … Continue reading "CRA Seminar by Aycin Aykutalp (Los Alamos National Laboratory)"

CRA Seminar by Dr. Ali Kheirandish (University of Wisconsin)

Web: https://icecube.wisc.edu/~akheirandish/ Title: Cosmic Neutrinos and the Unique Insights They Provide into the High-Energy Universe Abstract: The era of high-energy astrophysics with cosmic neutrinos began with the discovery of high-energy neutrinos with extraterrestrial origin in IceCube. The observation of high-energy cosmic neutrino flux revealed the prominent and larger than expected role of hadronic interactions in … Continue reading "CRA Seminar by Dr. Ali Kheirandish (University of Wisconsin)"

CRA Seminar by Dr. Pedro Capelo (University of Zurich)

Web: https://www.ics.uzh.ch/~pcapelo/index.html Title: Dual active galactic nuclei and the pairing of supermassive black holes in the LISA era Abstract: Pairs of accreting supermassive black holes (SMBHs), known as dual active galactic nuclei (AGN), and the generation of gravitational waves (GWs) from the inspiral and coalescence of SMBHs are two faces of the same coin. The … Continue reading "CRA Seminar by Dr. Pedro Capelo (University of Zurich)"

CRA Seminar by Prof. Nepomuk Otte (Georgia Tech)

Trinity: An air shower imaging instrument to detect ultrahigh-energy neutrinos The detection of neutrinos with IceCube has cracked open a new window in astrophysics at the TeV-PeV energy scale. The revelation of a relatively hard neutrino spectrum and the unknown origin of the flux are two motivations to extend neutrino measurements to even higher energies, … Continue reading "CRA Seminar by Prof. Nepomuk Otte (Georgia Tech)"

CRA Seminar by Prof. Preethi Nair (University of Alabama)

Web: https://physics.ua.edu/profiles/preethi-nair/ Title: Constraining the Demographics of Accreting Supermassive Black Holes and their Role in Galaxy Quenching in the nearby Universe Understanding the mechanisms which trigger an Active Galactic Nuclei (AGN or accreting supermassive black hole) and the role of these AGN in galaxy evolution, specifically in regulating or quenching star formation in galaxies, is … Continue reading "CRA Seminar by Prof. Preethi Nair (University of Alabama)"
