3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper I. Overall Architecture and Scientific Mission
Yong-Woo Kang, Sang Hyun Lee, Juhan Kim +22
We present the preliminary science concept and mission architecture of a 3.5-meter segmented-mirror robotic space telescope currently under study. The observatory is conceived as a…
3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper V. Key Scientific Mission: Compact-Object Time-Domain Science
Juhan Kim, Yong-Woo Kang, Sang Hyun Lee +22
An isolated compact object retains the point-source resolving power of the space-based slitless spectrograph. The baseline wavelength range is 0.2--1.5 m. The planning baseline…
3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper IV. Key Scientific Mission: Solar-System Small Bodies and Planetary Defense
Juhan Kim, Yong-Woo Kang, Sang Hyun Lee +22
The baseline 0.2--1.5 m observatory provides rapid-response astrometry, visible and near-infrared taxonomy, rotation and phase curves, recovery, and long-arc orbit improvement f…
3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper III. Key Scientific Mission: Exoplanet Science with a Coronagraph
Juhan Kim, Sang Hyun Lee, Yong-Woo Kang +22
This volume defines the exoplanet science program enabled by the dedicated high-contrast coronagraph in the baseline science payload of the 3.5-meter Segmented-Mirror Robotic Space…
3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper II. Key Scientific Mission: Wide-Field Cosmology and Galaxy Evolution
Juhan Kim, Yong-Woo Kang, Sang Hyun Lee +22
The 3.5-meter Segmented-Mirror Robotic Space Telescope uses an image slicer for all spectroscopic observations. The planning baseline uses for the wide survey and r…
Recycled Gas Dominates the Metal-rich Fuel of Supermassive Black Holes
Dongyun Kwak, Ena Choi, Hannah Jhee +5
Understanding the origin and chemical properties of gas accreted by supermassive black holes (SMBHs) is essential for linking black hole growth to galaxy evolution. Using a suite o…
Modeling Dependence Structures in Astronomical Multi-Band Time Series Data via Multi-Output Gaussian Processes
Samata Das, Lishan Shi, Yasaman Hamayouni +2
Modern astronomical time-domain surveys routinely collect multi-band light curves that provide complementary information about the physical processes governing source variability.…
Comparing the Near-infrared Spectral Energy Distributions from Different Stellar Population Synthesis Models with SPHEREx Observations
Jeong Hwan Lee, Minjin Kim, Woong-Seob Jeong +17
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…
Can BLR line profile shape improve single-epoch black hole mass estimates?
Lizvette Villafaña, Tommaso Treu, Shu Wang +7
The virial coefficient (), which is meant to encapsulate broad-line region (BLR) geometry and kinematics, remains one of the largest sources of systematic uncertainty in black h…
Dynamical Modeling of the Broad-Line Region with High-Mass Active Galactic Nuclei and Constraints on the Virial Factor
Shu Wang, Jong-Hak Woo, Lizvette Villafaña +2
We present the results of broad-line region (BLR) dynamical modeling for eight high-mass active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project, by…
BASS. LI. Cool gas supply of HI-massive local Seyfert galaxies
Jeein Kim, Aeree Chung, O. Ivy Wong +19
We present neutral atomic hydrogen (HI) imaging observations of 22 HI-rich (), hard X-ray-selected local Seyferts to explore how cool gas is su…
New black hole mass calibrations and the fundamental plane of the broad-line region size, luminosity, and velocity
