The Rise and Fall of ASASSN-18pg: Following a TDE from Early To Late Times
Thomas W. -S. Holoien, Katie Auchettl, Michael A. Tucker +29
We present nearly 500 days of observations of the tidal disruption event ASASSN-18pg, spanning from 54 days before peak light to 441 days after peak light. Our dataset includes X-r…
A multi-wavelength study of nearby millisecond pulsar PSR J14001431: improved astrometry & an optical detection of its cool white dwarf companion
Joseph K. Swiggum, David L. Kaplan, Maura A. McLaughlin +16
In 2012, five high school students involved in the Pulsar Search Collaboratory discovered the millisecond pulsar PSR J14001431 and initial timing parameters were published in Ro…
Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
The 2009 multiwavelength campaign on Mrk 421: Variability and correlation studies
MAGIC Collaboration, J. Aleksić, S. Ansoldi +270
We performed a 4.5-month multi-instrument campaign (from radio to VHE gamma rays) on Mrk421 between January 2009 and June 2009, which included VLBA, F-GAMMA, GASP-WEBT, Swift, RXTE…
Short GRB 130603B: Discovery of a jet break in the optical and radio afterglows, and a mysterious late-time X-ray excess
Wen-fai Fong, Edo Berger, Brian D. Metzger +13
We present radio, optical/NIR, and X-ray observations of the afterglow of the short-duration 130603B, and uncover a break in the radio and optical bands at 0.5 d after the burst, b…
Circumstellar Material in Type Ia Supernovae via Sodium Absorption Features
Assaf Sternberg, Avishay Gal-Yam, Josh D. Simon +17
Type Ia supernovae are key tools for measuring distances on a cosmic scale. They are generally thought to be the thermonuclear explosion of an accreting white dwarf in a close bina…
