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…
Extraplanar H II Regions in Spiral Galaxies. II. In Situ Star Formation in the Interstellar Thick Disk of NGC 4013
J. Christopher Howk, Katherine M. Rueff, Nicolas Lehner +3
We present observations of an H emitting knot in the thick disk of NGC 4013, demonstrating it is an H II region surrounding a cluster of young hot stars pc above the p…
Extraplanar H II Regions in Spiral Galaxies. I. Low-Metallicity Gas Accreting through the Disk-Halo Interface of NGC 4013
J. Christopher Howk, Katherine M. Rueff, Nicolas Lehner +3
The interstellar thick disks of galaxies serve as the interface between the thin star-forming disk, where feedback-driven outflows originate, and the distant halo, the repository f…
After The Fall: The Dust and Gas in E+A Post-Starburst Galaxies
A. Smercina, J. D. T. Smith, D. A. Dale +11
The traditional picture of post-starburst galaxies as dust- and gas-poor merger remnants, rapidly transitioning to quiescence, has been recently challenged. Unexpected detections o…
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…
First Results from the and ALMA Spectroscopic Surveys of the SMC: The Relationship Between [CII]-bright Gas and CO-bright Gas at Low Metallicity
Katherine E. Jameson, Alberto D. Bolatto, Mark Wolfire +15
The Small Magellanic Cloud (SMC) provides the only laboratory to study the structure of molecular gas at high resolution and low metallicity. We present results from the Herschel S…
