Two Long-Period Cataclysmic Variable Stars: ASASSN-14ho and V1062 Cyg
L. Claire Gasque, Callum A. Hening, Raphael E. Hviding +5
We report spectroscopy and photometry of the cataclysmic variable stars ASASSN-14ho and V1062 Cyg. Both are dwarf novae with spectra dominated by their secondary stars, which we cl…
Two years of non-thermal emission from the binary neutron star merger GW170817: rapid fading of the jet afterglow and first constraints on the kilonova fastest ejecta
A. Hajela, R. Margutti, K. D. Alexander +27
We present Chandra and VLA observations of GW170817 at ~521-743 days post merger, and a homogeneous analysis of the entire Chandra data set. We find that the late-time non-thermal…
The Optical Afterglow of GW170817: An Off-axis Structured Jet and Deep Constraints on a Globular Cluster Origin
Wen-fai Fong, P. K. Blanchard, K. D. Alexander +25
We present a revised and complete optical afterglow light curve of the binary neutron star merger GW170817, enabled by deep Hubble Space Telescope (HST) F606W observations at $\app…
A Galaxy-Targeted Search for the Optical Counterpart of the Candidate NS-BH Merger S190814bv with Magellan
S. Gomez, G. Hosseinzadeh, P. S. Cowperthwaite +13
On 2019 August 14 the Laser Interferometer Gravitational Wave Observatory (LIGO) and the Virgo gravitational wave interferometer announced the detection of a binary merger, S190814…
Searches After Gravitational-waves Using ARizona Observatories (SAGUARO): System Overview and First Results from Advanced LIGO/Virgo's Third Observing Run
M. J. Lundquist, K. Paterson, W. Fong +53
We present Searches After Gravitational-waves Using ARizona Observatories (SAGUARO), a comprehensive effort dedicated to the discovery and characterization of optical counterparts…
Follow-up of the Neutron Star Bearing Gravitational Wave Candidate Events S190425z and S190426c with MMT and SOAR
G. Hosseinzadeh, P. S. Cowperthwaite, S. Gomez +23
On 2019 April 25.346 and 26.640 UT the LIGO and Virgo gravitational wave (GW) observatories announced the detection of the first candidate events in Observing Run 3 that contain at…
High-speed photometry of faint cataclysmic variables - IX. Targets from multiple transient surveys
K. Paterson, P. A. Woudt, B. Warner +5
We present high-speed photometric observations of 25 cataclysmic variables detected by the All Sky Automated Search for Super-Novae (ASAS-SN), the Mobile Astronomical System of the…
A Taxonomic Study of Asteroid Families from KMTNet-SAAO Multi-band Photometry
N. Erasmus, A. McNeill, M. Mommert +3
We present here multi-band photometry for over 2000 Main-belt asteroids. For each target we report the probabilistic taxonomy using the measured V-R and V-I colors in combination w…
Gravitational wave cosmology and astrophysics with large spectroscopic galaxy surveys
Antonella Palmese, Or Graur, James T. Annis +12
During the next decade, gravitational waves will be observed from hundreds of binary inspiral events. When the redshifts of the host galaxies are known, these events can be used as…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
Gravity and Light: Combining Gravitational Wave and Electromagnetic Observations in the 2020s
R. J. Foley, K. D. Alexander, I. Andreoni +110
As of today, we have directly detected exactly one source in both gravitational waves (GWs) and electromagnetic (EM) radiation, the binary neutron star merger GW170817, its associa…
