Processing Images from the Zwicky Transient Facility

TLDR
The Zwicky Transient Facility as mentioned in this paper is a robotic-observing program, in which a newly engineered 600-MP digital camera with a pioneeringly large field of view, 47 square degrees, will be installed into the 48-inch Samuel Oschin Telescope at the Palomar Observatory.
Abstract
The Zwicky Transient Facility is a new robotic-observing program, in which a newly engineered 600-MP digital camera with a pioneeringly large field of view, 47 square degrees, will be installed into the 48-inch Samuel Oschin Telescope at the Palomar Observatory. The camera will generate ~1 petabyte of raw image data over three years of operations. In parallel related work, new hardware and software systems are being developed to process these data in real time and build a long-term archive for the processed products. The first public release of archived products is planned for early 2019, which will include processed images and astronomical-source catalogs of the northern sky in the g and r bands. Source catalogs based on two different methods will be generated for the archive: aperture photometry and point-spread-function fitting.

Supernova PTF12glz: a possible shock breakout driven through an aspherical wind

TL;DR: In this article, the authors present visible-light and ultraviolet (UV) observations of the supernova PTF12glz and show that at early times, while the freely expanding ejecta are presumably masked by the optically thick CSM, the radius of the blackbody that best fits the observations grows at ~7000 km/s.

Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties

Anthony G. A. Brown, +590 more
TL;DR: The first Gaia data release, Gaia DR1 as discussed by the authors, consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the Hipparcos and Tycho-2 catalogues.

Proper Image Subtraction—Optimal Transient Detection, Photometry, and Hypothesis Testing

TL;DR: In this paper, the authors derived a closed-form statistic for transient detection, flux measurement, and any image-difference hypothesis testing, which is mathematically proven to be the optimal transient detection statistic in the limit of background-dominated noise.
