The search for failed supernovae with the Large Binocular Telescope: a new candidate and the failed SN fraction with 11 yr of data
J. M. M. Neustadt, C. S. Kochanek, K. Z. Stanek +5
We present updated results of the Large Binocular Telescope Search for Failed Supernovae. This search monitors luminous stars in 27 nearby galaxies with a current baseline of 11~yr…
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…
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…
The Massive Star Population in M101. III. Spectra and Photometry of the Luminous and Variable Stars
Skyler H. Grammer, Roberta M. Humphreys, Jill Gerke
We discuss moderate resolution spectra, multicolor photometry, and light curves of thirty-one of the most luminous stars and variables in the giant spiral M101. The majority are in…
The Cepheid distance to the maser-host galaxy NGC 4258: Studying systematics with the Large Binocular Telescope
M. M. Fausnaugh, C. S. Kochanek, J. R. Gerke +3
We identify and phase a sample of 81 Cepheids in the maser-host galaxy NGC 4258 using the Large Binocular Telescope (LBT), and obtain calibrated mean magnitudes in up to 4 filters…
The Search for Failed Supernovae with The Large Binocular Telescope: First Candidates
J. R. Gerke, C. S. Kochanek, K. Z. Stanek
We are monitoring 27 galaxies within 10 Mpc using the Large Binocular Telescope to search for failed supernovae (SNe), massive stars that collapse to form a black hole without a SN…
Finding Car Analogs in Nearby Galaxies Using Spitzer: II. Identification of An Emerging Class of Extragalactic Self-Obscured Stars
Rubab Khan, C. S. Kochanek, K. Z. Stanek +1
Understanding the late-stage evolution of the most massive stars such as Carinae is challenging because no true analogs of Car have been clearly identified in the Milky Way…
The Mid-IR Contribution Of Dust Enshrouded Stars In Six Nearby Galaxies
J. R. Gerke, C. S. Kochanek
We measure the integrated contributions of dusty AGB stars and other luminous red mid-IR sources to the mid-IR luminosities of 6 galaxies (M81, NGC 2403, NGC 300, M33 and the Magel…
Discovery of Variability of the Progenitor of SN 2011dh in M51 Using the Large Binocular Telescope
D. M. Szczygieł, J. R. Gerke, C. S. Kochanek +1
We show that the candidate progenitor of the core-collapse SN 2011dh in M51 (8 Mpc away) was fading by 0.039 +- 0.006 mag/year during the three years prior to the supernova, and th…
A Near-Infrared Survey of the Inner Galactic Plane for Wolf-Rayet Stars II. Going Fainter: 71 More New WR Stars
Michael M. Shara, Jacqueline K. Faherty, David Zurek +5
We are continuing a J, K and narrow-band imaging survey of 300 square degrees of the plane of the Galaxy, searching for new Wolf-Rayet stars. Our survey spans 150 degrees in Galact…
A Study of Cepheids in M81 with the Large Binocular Telescope (Efficiently Calibrated with HST)
J. R. Gerke, C. S. Kochanek, J. L. Prieto +2
We identify and phase a sample of 107 Cepheids with 10<P/days<100 in M81 using the LBT and calibrate their BVI mean magnitudes with archival HST data. The use of a ground-based tel…
A Near-Infrared Survey of the Inner Galactic Plane for Wolf-Rayet Stars I. Methods and First Results: 41 New WR Stars
Michael M. Shara, Anthony F. J. Moffat, Jill Gerke +6
The discovery of new Wolf-Rayet (WR) stars in our Galaxy via large-scale narrowband optical surveys has been severely limited by dust extinction. Recent improvements in infrared te…
Polars Changing State: Multiwavelength Long Term Photometry and Spectroscopy of QS Tel, V834 Cen, and BL Hyi
Jill R. Gerke, Steve B. Howell, Frederick M. Walter
Long term optical and near-infrared photometric and blue spectroscopic observations were obtained for QS Tel, V834 Cen, and BL Hyi. The optical light curves of all three polars dis…
