Target of Opportunity Observations of Gravitational Wave Events with LSST
R. Margutti, P. Cowperthwaite, Z. Doctor +79
The discovery of the electromagnetic counterparts to the binary neutron star merger GW170817 has opened the era of GW+EM multi-messenger astronomy. Exploiting this breakthrough req…
A strategy for LSST to unveil a population of kilonovae without gravitational-wave triggers
Igor Andreoni, Shreya Anand, Federica B. Bianco +10
We present a cadence optimization strategy to unveil a large population of kilonovae using optical imaging alone. These transients are generated during binary neutron star and pote…
Presto-Color: A Photometric Survey Cadence for Explosive Physics & Fast Transients
Federica B. Bianco, Maria R. Drout, Melissa L. Graham +6
We identify minimal observing cadence requirements that enable photometric astronomical surveys to detect and recognize fast and explosive transients and fast transient features. O…
A Search for Optical Emission from Binary-Black-Hole Merger GW170814 with the Dark Energy Camera
Z. Doctor, R. Kessler, K. Herner +96
Binary black hole (BBH) mergers found by the LIGO and Virgo detectors are of immense scientific interest to the astrophysics community, but are considered unlikely to be sources of…
LSST Target-of-Opportunity Observations of Gravitational Wave Events: Essential and Efficient
P. S. Cowperthwaite, V. A. Villar, D. M. Scolnic +1
We present simulated observations to assess the ability of LSST and the WFD survey to detect and characterize kilonovae - the optical emission associated with binary neutron star (…
Spitzer Space Telescope Infrared Observations of the Binary Neutron Star Merger GW170817
V. A. Villar, P. S. Cowperthwaite, E. Berger +12
We present Spitzer Space Telescope 3.6 and 4.5 micron observations of the binary neutron star merger GW170817 at 43, 74, and 264 days post-merger. Using the final observation as a…
A Decline in the X-ray through Radio Emission from GW170817 Continues to Support an Off-Axis Structured Jet
K. D. Alexander, R. Margutti, P. K. Blanchard +17
We present new observations of the binary neutron star merger GW170817 at days post-merger, at radio (Karl G. Jansky Very Large Array; VLA), X-ray (Chandra X-ra…
Open Astronomy Catalogs API
James Guillochon, Philip S. Cowperthwaite
We announce the public release of the application program interface (API) for the Open Astronomy Catalogs (OACs), the OACAPI. The OACs serve near-complete collections of supernova,…
A Precise Distance to the Host Galaxy of the Binary Neutron Star Merger GW170817 Using Surface Brightness Fluctuations
Michele Cantiello, J. B. Jensen, J. P. Blakeslee +25
The joint detection of gravitational waves and electromagnetic radiation from the binary neutron star (BNS) merger GW170817 has provided unprecedented insight into a wide range of…
The Binary Neutron Star event LIGO/VIRGO GW170817 a hundred and sixty days after merger: synchrotron emission across the electromagnetic spectrum
Raffaella Margutti, K. D. Alexander, X. Xie +17
We report deep Chandra, HST and VLA observations of the binary neutron star event GW170817 at d after merger. These observations show that GW170817 has been steadily bright…
