Multiphase Analysis of (U)LIRG Nuclear Activity (MAUNA). I. Spatially Resolved Optical Emission-Line Diagnostics
Justin A. Kader, Vivian U, Marina Bianchin +33
We present resolved optical integral-field spectroscopy of the 32 luminous and ultraluminous infrared galaxy systems of the Multiphase Analysis of (U)LIRG Nuclear Activity (MAUNA)…
Euclid: Discovery of 31 new quasars at
D. Yang, J. F. Hennawi, F. Guarneri +211
We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…
Clumpy Disk, Interloper, or Merger? Nature of a Distant Galaxy Pair at 5 kpc Projected Separation
Hajar Aziz, Vivian U, Archana Aravindan +8
We present the morphological, photometric, and spectroscopic properties of a z ~ 1 galaxy, "lil gal", serendipitously detected in JWST Mid Infrared Instrument (MIRI) images of near…
The Multi-phase Biconical Outflow in the local IR-Luminous Merger IRASF01364-1042
Y. Song, V. U, J. Kader +37
We investigate the spatially-resolved ISM properties of the local (), IR-luminous (\,L), late-stage galaxy merger IRAS F01364-1042, comb…
Detection of an Extended Ly Halo around a Broad Absorption Line Quasar with the Keck Cosmic Web Imager
Raymond P. Remigio, Aaron J. Barth, Feige Wang +6
We present the first results from a program searching for extended Ly halos around high redshift () quasars using the red channel of the Keck Cosmic Web Imager (…
The Host Galaxies of Active Galactic Nuclei with Direct Black Hole Mass Measurements
Vardha N. Bennert, Nico Winkel, Tommaso Treu +13
Reverberation mapping (RM) determines the mass of black holes (BH) in active galactic nuclei (AGNs) by resolving the BH gravitational sphere of influence in the time domain. Recent…
A precessing jet from an active galactic nucleus drives gas outflow from a disk galaxy
Justin A. Kader, Vivian U, Loreto Barcos-Muñoz +30
To reproduce observed galaxy properties, cosmological simulations require that massive galaxies experience feedback from active galactic nuclei, which regulates star formation with…
Spatially Resolved [O III] Emission Line Kinematics of Reverberation-Mapped AGNs with the Keck Cosmic Web Imager
Raymond P. Remigio, Vivian U, Aaron J. Barth +8
We present optical integral-field spectroscopic data of ten nearby () Seyfert 1 galaxies taken with the Keck Cosmic Web Imager (KCWI). We map the spatially re…
Shockingly Effective: Cluster Winds as Engines of Feedback in Starburst Galaxy VV 114
Justin A. Kader, Vivian U, Jeffrey A. Rich +29
We present high-resolution Keck Cosmic Web Imager (KCWI) and MUSE IFU spectroscopy of VV 114, a local infrared-luminous merger undergoing a vigorous starburst and showing evidence…
Combining Direct Black Hole Mass Measurements and Spatially Resolved Stellar Kinematics to Calibrate the - Relation of Active Galaxies
Nico Winkel, Vardha N. Bennert, Raymond P. Remigio +8
The origin of the tight scaling relation between the mass of supermassive black holes (SMBHs; ) and their host-galaxy properties remains unclear. Active galactic nuclei…
GOALS-JWST: Gas Dynamics and Excitation in NGC7469 revealed by NIRSpec
Marina Bianchin, Vivian U, Yiqing Song +36
We present new JWST-NIRSpec IFS data for the luminous infrared galaxy NGC7469: a nearby (70.6Mpc) active galaxy with a Sy 1.5 nucleus that drives a highly ionized gas outflow and a…
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…
Optical Continuum Reverberation in the Dwarf Seyfert Nucleus of NGC 4395
John W. Montano, Hengxiao Guo, Aaron J. Barth +4
The nearby dwarf spiral galaxy NGC 4395 contains a broad-lined active galactic nucleus (AGN) of exceptionally low luminosity powered by accretion onto a central black hole of very…
The Paschen Jump as a Diagnostic of the Diffuse Nebular Continuum Emission in Active Galactic Nuclei
Hengxiao Guo, Aaron J. Barth, Kirk T. Korista +17
Photoionization modeling of active galactic nuclei (AGN) predicts that diffuse continuum (DC) emission from the broad-line region makes a substantial contribution to the total cont…
