The Search for Failed Supernovae with the Large Binocular Telescope: N6946-BH1, Still No Star
C. M. Basinger, C. S. Kochanek, S. M. Adams +2
We present new Large Binocular Telescope, Hubble Space Telescope, and Spitzer Space Telescope data for the failed supernova candidate N6946-BH1. We also report an unsuccessful atte…
Deep Late-Time Observations of the Supernova Impostors SN 1954J and SN 1961V
Rachel A. Patton, C. S. Kochanek, S. M. Adams
SN 1954J in NGC 2403 and SN 1961V in NGC 1058 were two luminous transients whose definitive classification as either non-terminal eruptions or supernovae remains elusive. A critica…
Velocity-resolved reverberation mapping of five bright Seyfert 1 galaxies
G. De Rosa, M. M. Fausnaugh, C. J. Grier +99
We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our ma…
Continuum Reverberation Mapping of the Accretion Disks in Two Seyfert 1 Galaxies
M. M. Fausnaugh, D. A. Starkey, Keith Horne +69
We present optical continuum lags for two Seyfert 1 galaxies, MCG+08-11-011 and NGC 2617, using monitoring data from a reverberation mapping campaign carried out in 2014. Our light…
The quiescent progenitors of four Type II-P/L supernovae
Samson A. Johnson, C. S. Kochanek, S. M. Adams
We present Large Binocular Telescope difference imaging data for the final years of four Type II-P/L supernovae progenitors. For all four, we find no significant evidence for stoch…
Illuminating Gravitational Waves: A Concordant Picture of Photons from a Neutron Star Merger
M. M. Kasliwal, E. Nakar, L. P. Singer +78
Merging neutron stars offer an exquisite laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an…
On the Progenitor of the Type Ic Supernova 2012fh
Samson A. Johnson, C. S. Kochanek, S. M. Adams
Little is observationally known about the progenitors of Type Ibc supernovae (SNe) or the typical activity of SNe progenitors in their final years. Here, we analyze deep Large Bino…
Space Telescope and Optical Reverberation Mapping Project. V. Optical Spectroscopic Campaign and Emission-Line Analysis for NGC 5548
L. Pei, M. M. Fausnaugh, A. J. Barth +153
We present the results of an optical spectroscopic monitoring program targeting NGC 5548 as part of a larger multi-wavelength reverberation mapping campaign. The campaign spanned s…
The Search for Failed Supernovae with the Large Binocular Telescope: Constraints from 7 Years of Data
S. M. Adams, C. S. Kochanek, J. R. Gerke +1
We report updated results for the first 7 years of our program to monitor 27 galaxies within 10 Mpc using the Large Binocular Telescope to search for failed supernovae (SNe) -- cor…
Reverberation Mapping of Optical Emission Lines in Five Active Galaxies
M. M. Fausnaugh, C. J. Grier, M. C. Bentz +68
We present the first results from an optical reverberation mapping campaign executed in 2014, targeting the active galactic nuclei (AGN) MCG+08-11-011, NGC 2617, NGC 4051, 3C 382,…
The search for failed supernovae with the Large Binocular Telescope: confirmation of a disappearing star
S. M. Adams, C. S. Kochanek, J. R. Gerke +2
We present Hubble Space Telescope imaging confirming the optical disappearance of the failed supernova (SN) candidate identified by Gerke et al. (2015). This re…
Almost Gone: SN~2008S and NGC~300 2008OT-1 are Fainter than their Progenitors
S. M. Adams, C. S. Kochanek, J. L. Prieto +3
We present late-time Hubble and Spitzer Space Telescope imaging of SN 2008S and NGC 300 2008OT-1, the prototypes of a common class of stellar transients whose true nature is debate…
