On the rate of black hole binary mergers in galactic nuclei due to dynamical hardening
Nathan W. C. Leigh, Aaron M. Geller, B. McKernan +9
We assess the contribution of dynamical hardening by direct three-body scattering interactions to the rate of stellar-mass black hole binary (BHB) mergers in galactic nuclei. We de…
iPTF Survey for Cool Transients
S. M. Adams, N. Blagorodnova, M. M. Kasliwal +25
We performed a wide-area (2000 deg) g and I band experiment as part of a two month extension to the Intermediate Palomar Transient Factory. We discovered 36 extragalactic tra…
AGN photoionization of gas in companion galaxies as a probe of AGN radiation in time and direction
William C. Keel, Vardha N. Bennert, Anna Pancoast +9
We consider AGN photoionization of gas in companion galaxies (cross-ionization) as a way to sample the intensity of AGN radiation in both direction and time, independent of the gas…
Illuminating Gravitational Waves: A Concordant Picture of Photons from a Neutron Star Merger
M. M. Kasliwal, E. Nakar, L. P. Singer +78
Merging neutron stars offer an exquisite laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an…
The Redshift Completeness of Local Galaxy Catalogs
S. R. Kulkarni, D. A. Perley, A. A. Miller
There is considerable interest in understanding the demographics of galaxies within the local universe (defined, for our purposes, as the volume within a radius of 200 Mpc or z<0.0…
Planet Four: Terrains - Discovery of Araneiforms Outside of the South Polar Layered Deposits
Megan E. Schwamb, Klaus-Michael Aye, Ganna Portyankina +7
We present the results of a systematic mapping of seasonally sculpted terrains on the South Polar region of Mars with the Planet Four: Terrains (P4T) online citizen science project…
