THE MAN BEHIND THE CURTAIN: X-RAYS DRIVE THE UV THROUGH NIR VARIABILITY IN THE 2013 ACTIVE GALACTIC NUCLEUS OUTBURST IN NGC 2617
- B. Shappee, J. Prieto, +44 authors Y. Yoon
- Physics
- 8 October 2013
After the All-Sky Automated Survey for SuperNovae discovered a significant brightening of the inner region of NGC 2617, we began a ∼70 day photometric and spectroscopic monitoring campaign from the… Expand
Six months of multiwavelength follow-up of the tidal disruption candidate asassn-14li and implied tde rates from asas-sn
- T. Holoien, C. Kochanek, +21 authors P. Wozniak
- Physics
- 6 July 2015
We present ground-based and Swift photometric and spectroscopic observations of the candidate tidal disruption event (TDE) ASASSN-14li, found at the center of PGC043234 (d ' 90 Mpc) by the All-Sky… Expand
Revealing the High-Redshift Star Formation Rate with Gamma-Ray Bursts
- H. Yuksel, M. Kistler, J. Beacom, A. Hopkins
- Physics
- 25 April 2008
While the high-z frontier of star formation rate (SFR) studies has advanced rapidly, direct measurements beyond -->z ~ 4 remain difficult, as shown by significant disagreements among different… Expand
THE STAR FORMATION RATE IN THE REIONIZATION ERA AS INDICATED BY GAMMA-RAY BURSTS
- M. Kistler, H. Yuksel, J. Beacom, A. Hopkins, J. Wyithe
- Physics
- 2 June 2009
High-redshift gamma-ray bursts (GRBs) offer an extraordinary opportunity to study aspects of the early universe, including the cosmic star formation rate (SFR). Motivated by the two recent highest-z… Expand
Characterizing Supernova Progenitors via the Metallicities of their Host Galaxies, from Poor Dwarfs to Rich Spirals
We investigate how the different types of supernovae are relatively affected by the metallicity of their host galaxy. We match the SAI supernova catalog to the SDSS DR4 catalog of star-forming… Expand
ASASSN-15oi: a rapidly evolving, luminous tidal disruption event at 216 Mpc
- T. Holoien, C. Kochanek, +17 authors M. Seibert
- Physics
- 2 February 2016
We present ground-based and Swift photometric and spectroscopic observations of the tidal disruption event (TDE) ASASSN-15oi, discovered at the center of 2MASX J20390918-3045201 ($d\simeq216$ Mpc) by… Expand
The Cosmic Core-collapse Supernova Rate does not match the Massive-Star Formation Rate
- S. Horiuchi, J. Beacom, C. Kochanek, J. Prieto, K. Stanek, T. Thompson
- Physics
- 9 February 2011
We identify a "supernova rate problem": the measured cosmic core-collapse supernova rate is a factor of ~ 2 smaller (with significance ~ 2 sigma) than that predicted from the measured cosmic… Expand
Neutrino Physics with JUNO
- F. An, G. An, +224 authors Jiaheng Zou
- Physics
- 20 July 2015
The Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton multi-purpose underground liquid scintillator detector, was proposed with the determination of the neutrino mass hierarchy (MH) as a… Expand
An Unexpectedly Swift Rise in the Gamma-Ray Burst Rate
- M. Kistler, H. Yuksel, J. Beacom, K. Stanek
- Physics
- 4 September 2007
The association of long gamma-ray bursts with supernovae naturally suggests that the cosmic GRB rate should trace the star formation history. Finding otherwise would provide important clues… Expand
ASASSN-15lh: A highly super-luminous supernova
- S. Dong, B. Shappee, +27 authors P. Wozniak
- Physics, Medicine
- Science
- 10 July 2015
The most luminous supernova to date Supernovae are exploding stars at the end of their lives, providing an input of heavy elements and energy into galaxies. Some types have near-identical peak… Expand
