TOROS Optical follow-up of the Advanced LIGO-VIRGO O2 second observational campaign
Rodolfo Artola, Martin Beroiz, Juan Cabral +48
We present the results of the optical follow-up, conducted by the TOROS collaboration, of gravitational wave events detected during the Advanced LIGO-Virgo second observing run (No…
Significant Luminosity Differences of Two Twin Type Ia Supernovae
Ryan J. Foley, Samantha L. Hoffmann, Lucas M. Macri +5
The Type Ia supernovae (SNe Ia) 2011by, hosted in NGC 3972, and 2011fe, hosted in M101, are optical "twins," having almost identical optical light-curve shapes, colours, and near-m…
Observations of the first electromagnetic counterpart to a gravitational wave source by the TOROS collaboration
M. C. Díaz, L. M. Macri, D. Garcia Lambas +52
We present the results of prompt optical follow-up of the electromagnetic counterpart of the gravitational-wave event GW170817 by the Transient Optical Robotic Observatory of the S…
GW150914: First search for the electromagnetic counterpart of a gravitational-wave event by the TOROS collaboration
Mario C. Díaz, Martín Beroiz, Tania Peñuela +31
We present the results of the optical follow-up conducted by the TOROS collaboration of the first gravitational-wave event GW150914. We conducted unfiltered CCD observations (0.35-…
Detection of a Light Echo from the Otherwise Normal SN 2007af
D. Drozdov, M. D. Leising, P. A. Milne +5
We present the discovery of a light echo from SN 2007af, a normal Type Ia supernova (SN Ia) in NGC 5584. Hubble Space Telescope (HST) images taken three years post explosion reveal…
