The Palomar-Quest Digital Synoptic Sky Survey
S. G. Djorgovski, C. Baltay, A. A. Mahabal +10
We describe briefly the Palomar-Quest (PQ) digital synoptic sky survey, including its parameters, data processing, status, and plans. Exploration of the time domain is now the cent…
Supplement: Localization and broadband follow-up of the gravitational-wave transient GW150914
B. P. Abbott, R. Abbott, T. D. Abbott +1538
This Supplement provides supporting material for arXiv:1602.08492 . We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the c…
Localization and broadband follow-up of the gravitational-wave transient GW150914
B. P. Abbott, R. Abbott, T. D. Abbott +1538
A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The e…
First Results from the La Silla-QUEST Supernova Survey and the Carnegie Supernova Project
E. S. Walker, C. Baltay, A. Campillay +20
The LaSilla/QUEST Variability Survey (LSQ) and the Carnegie Supernova Project (CSP II) are collaborating to discover and obtain photometric light curves for a large sample of low r…
Massive stars exploding in a He-rich circumstellar medium. VI. Observations of two distant Type Ibn supernova candidates discovered by La Silla-QUEST
A. Pastorello, E. Hadjiyska, D. Rabinowitz +31
We present optical observations of the peculiar stripped-envelope supernovae (SNe) LSQ12btw and LSQ13ccw discovered by the La Silla-QUEST survey. LSQ12btw reaches an absolute peak…
Optical photometry and spectroscopy of the low-luminosity, broad-lined Ic supernova iPTF15dld
E. Pian, L. Tomasella, E. Cappellaro +37
Core-collapse stripped-envelope supernova (SN) explosions reflect the diversity of physical parameters and evolutionary paths of their massive star progenitors. We have observed th…
Discovery of the Bright Trans-Neptunian Object 2000 EB173
Ignacio Ferrin, D. Rabinowitz, B. Schaefer +45
We describe the discovery circumstances and photometric properties of 2000 EB173, now one of the brightest trans-Neptunian objects (TNOs) with opposition magnitude m_R=18.9 and als…
Early ultraviolet emission in the Type Ia supernova LSQ12gdj: No evidence for ongoing shock interaction
R. A. Scalzo, M. Childress, B. Tucker +37
We present photospheric-phase observations of LSQ12gdj, a slowly-declining, UV-bright Type Ia supernova. Classified well before maximum light, LSQ12gdj has extinction-corrected abs…
The QUEST RR Lyrae Survey: Confirmation of the Clump at 50 kpc and Other Over-Densities in the Outer Halo
A. K. Vivas, R. Zinn, P. Andrews +33
We have measured the periods and light curves of 148 RR Lyrae variables from V=13.5 to 19.7 from the first 100 sq. degrees of the QUEST RR Lyrae survey. Approximately 55% of these…
Exploring the Time Domain with the Palomar-QUEST Sky Survey
A. Mahabal, S. G. Djorgovski, M. J. Graham +16
Exploration of the time variability on the sky over a broad range of flux levels and wavelengths is rapidly becoming a new frontier of astronomical research. We describe here brief…
LSQ14efd: observations of the cooling of a shock break-out event in a type Ic Supernova
C. Barbarino, M. T. Botticella, M. Dall'Ora +29
We present the photometric and spectroscopic evolution of the type Ic supernova LSQ14efd, discovered by the La Silla QUEST survey and followed by PESSTO. LSQ14efd was discovered fe…
La Silla QUEST RR Lyrae Star Survey: Region I
R. Zinn, B. Horowitz, A. K. Vivas +5
A search for RR Lyrae stars (RRLS) in 840 sq.deg. of the sky in right ascension 150 - 210 deg and declination -10 - +10 deg yielded 1013 type ab and 359 type c RRLS. This sample is…
Time Domain Explorations With Digital Sky Surveys
A. A. Mahabal, S. G. Djorgovski, M. J. Graham +17
One of the new frontiers of astronomical research is the exploration of time variability on the sky at different wavelengths and flux levels. We have carried out a pilot project us…
A Catalog of Compact Groups of Galaxies in the SDSS Commissioning Data
B. C. Lee, S. S. Allam, D. L. Tucker +20
Compact groups (CGs) of galaxies -- relatively poor groups of galaxies in which the typical separations between members is of the order of a galaxy diameter -- offer an exceptional…
