Comparing the Near-infrared Spectral Energy Distributions from Different Stellar Population Synthesis Models with SPHEREx Observations
Jeong Hwan Lee, Minjin Kim, Woong-Seob Jeong +16
While stellar population synthesis (SPS) models have been widely used for spectral analysis in optical wavelengths, their characteristics remain uncertain in the near-infrared (NIR…
A UV-to-Near-infrared QSO Composite Spectrum from the SPHEREx All-Sky Survey
Minjin Kim, Yongjung Kim, Woong-Seob Jeong +19
We present a composite spectrum of type 1 SDSS QSOs (median ), constructed using SPHEREx spectrophotometric data and covering a rest-frame wavelength…
Decoupled Kinematics and Excitation in the Compton-thick AGN NGC 6552: Spatially Resolved KOOLS-IFU Observations
Kyuseok Oh, Yoshihiro Ueda, Kanta Fujiwara +7
Hard X-ray selected Compton-thick AGNs provide a relatively obscuration-resistant census of accretion, but optical line diagnostics can be strongly shaped by extinction and geometr…
Hector Galaxy Survey: Optical IFU and Chandra Reveal a Low-Luminosity AGN Behind Extended LINER Emission
Kyuseok Oh, Gabriella Quattropani, Pratyush Kumar Das +25
We present evidence that the Hector Galaxy Survey galaxy C901005481609968 (), which exhibits spatially extended LINER-like emission in optical integral-field spe…
BASS LV. Connecting X-ray variability with AGN physical properties and a new path to Cosmological distances
Matilde Signorini, Federica Ricci, Alessia Tortosa +18
X-ray variability is a well-established characteristic of active galactic nuclei (AGN), known to correlate inversely with both the supermassive black hole mass and luminosity, alth…
Resolved UV-Optical HST Imaging and Spectral Energy Distribution Modeling of Nearby BAT Active Galactic Nuclei
Connor Auge, Michael Koss, Kriti K. Gupta +17
We use high-resolution UV-to-optical imaging from the Hubble Space Telescope (HST) to construct spatially resolved spectral energy distributions (SEDs) for seven nearby ()…
