NuSTAR Observes Two Bulgeless Galaxies: No Hard X-ray AGN Detected in NGC 4178 or J0851+3926
Ryan W. Pfeifle, Shobita Satyapal, Claudio Ricci +5
The discovery over the last several decades of moderate luminosity AGNs in disk-dominated galaxies - which show no "classical" bulges - suggests that secular mechanisms represent a…
The microvariability and wavelength dependence of polarization degree/angle of BL Lacertae in the outburst 2020 to 2021
Ryo Imazawa, Mahito Sasada, Natsuko Hazama +6
We have obtained simultaneous and continuous photo-polarization observations of the blazar BL Lacertae in optical and near-infrared (NIR) bands during a historical outburst from 20…
GOALS-JWST: Revealing the Buried Star Clusters in the Luminous Infrared Galaxy VV 114
Sean T. Linden, Aaron S. Evans, Lee Armus +30
We present the results of a {\it James Webb Space Telescope} NIRCam investigation into the young massive star cluster (YMC) population in the luminous infrared galaxy VV 114. We id…
GOALS-JWST: Resolving the Circumnuclear Gas Dynamics in NGC 7469 in the Mid-Infrared
Vivian U, Thomas Lai, Marina Bianchin +35
The nearby, luminous infrared galaxy (LIRG) NGC 7469 hosts a Seyfert nucleus with a circumnuclear star-forming ring and is thus the ideal local laboratory for investigating the sta…
GOALS-JWST: Mid-Infrared Spectroscopy of the Nucleus of NGC 7469
L. Armus, T. Lai, V. U +32
We present mid-infrared spectroscopic observations of the nucleus of the nearby Seyfert galaxy NGC 7469 taken with the MIRI instrument on the James Webb Space Telescope (JWST) as p…
GOALS-JWST: Unveiling Dusty Compact Sources in the Merging Galaxy IIZw096
Hanae Inami, Jason Surace, Lee Armus +30
We have used the Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) to obtain the first spatially resolved, mid-infrared (mid-IR) images of IIZw096, a merging…
GOALS-JWST: Tracing AGN Feedback on the Star-Forming ISM in NGC 7469
Thomas S. -Y. Lai, Lee Armus, Vivian U +34
We present James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI) integral-field spectroscopy of the nearby merging, luminous infrared galaxy, NGC 7469. This galaxy hosts…
GOALS-JWST: NIRCam and MIRI Imaging of the Circumnuclear Starburst Ring in NGC 7469
Thomas Bohn, Hanae Inami, Tanio Diaz-Santos +30
We present James Webb Space Telescope (JWST) imaging of NGC 7469 with the Near-Infrared Camera (NIRCam) and the Mid-InfraRed Instrument (MIRI). NGC 7469 is a nearby, , l…
GOALS-JWST: Hidden Star Formation and Extended PAH Emission in the Luminous Infrared Galaxy VV 114
Aaron S. Evans, David Frayer, Vassilis Charmandaris +32
James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI) images of the luminous infrared (IR) galaxy VV 114 are presented. This redshift ~ 0.020 merger has a western compon…
A Near-Infrared look at AGN Feedback in Bulgeless Galaxies
Thomas Bohn, Gabriela Canalizo, Shobita Satyapal +1
While it is generally believed that supermassive black holes (SMBH) lie in most galaxies with bulges, few SMBHs have been confirmed in bulgeless galaxies. Identifying such a popula…
The Lick AGN Monitoring Project 2016: Dynamical Modeling of Velocity-Resolved H\b{eta} Lags in Luminous Seyfert Galaxies
Lizvette Villafaña, Peter R. Williams, Tommaso Treu +62
We have modeled the velocity-resolved reverberation response of the H\b{eta} broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitioring…
