Using gas clouds to probe the accretion flow around SgrA*: G2's delayed pericenter passage
Ann-Marie Madigan, Michael McCourt, Ryan O'Leary
We study the dynamical evolution of the putative gas clouds G1 and G2 recently discovered in the Galactic center. Following earlier studies suggesting that these two clouds are par…
Dynamical formation signatures of black hole binaries in the first detected mergers by LIGO
Ryan M. O'Leary, Yohai Meiron, Bence Kocsis
The dynamical formation of stellar-mass black hole-black hole binaries has long been a promising source of gravitational waves for the Laser Interferometer Gravitational-Wave Obser…
Young and Millisecond Pulsar GeV Gamma-ray Fluxes from the Galactic Center and Beyond
Ryan M. O'Leary, Matthew D. Kistler, Matthew Kerr +1
Gamma-ray observations have shown pulsars to be efficient converters of rotational energy into GeV photons and it is of wide-ranging interest to determine their contribution to the…
Young Pulsars and the Galactic Center GeV Gamma-ray Excess
Ryan M. O'Leary, Matthew D. Kistler, Matthew Kerr +1
Studies of Fermi data indicate an excess of GeV gamma rays around the Galactic center (GC), possibly due to dark matter. We show that young gamma-ray pulsars can yield a similar si…
The Proper Motion of the Galactic Center Pulsar Relative to Sagittarius A*
Geoffrey C. Bower, Adam Deller, Paul Demorest +12
We measure the proper motion of the pulsar PSR J1745-2900 relative to the Galactic Center massive black hole, Sgr A*, using the Very Long Baseline Array (VLBA). The pulsar has a tr…
Turbovelocity Stars: Kicks Resulting From the Tidal Disruption of Solitary Stars
Haik Manukian, James Guillochon, Enrico Ramirez-Ruiz +1
The centers of most known galaxies host supermassive black holes (SMBHs). In orbit around these black holes are a centrally-concentrated distribution of stars, both in single and i…
