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…
Hector Galaxy Survey: Data Processing, Quality Control and Early Science
S. Oh, M. L. P. Gunawardhana, S. M. Croom +52
The Hector Galaxy Survey is a new optical integral field spectroscopy (IFS) survey currently using the AAT to observe up to 15,000 galaxies at low redshift (). The Hector…
Spatially Resolved Star Formation Rate and Dust Attenuation of Nearby Galaxies from CALIFA, GALEX, and WISE Data
Jong Chul Lee, Joon Hyeop Lee, Hyunjin Jeong +2
We study star formation rate (SFR) indicators and dust attenuation of 74 nearby star-forming galaxies on kiloparsec scales, based on GALEX far-ultraviolet (FUV) and WISE mid-infrar…
Impact of Internal Dust Correction on the Stellar Populations of Galaxies Estimated Using the Full Spectrum Fitting
Joon Hyeop Lee, Hyunjin Jeong, Jiwon Chung +2
Full spectrum fitting is a powerful tool for estimating the stellar populations of galaxies, but the fitting results are often significantly influenced by internal dust attenuation…
One-sided H alpha Excess before the First Pericentre Passage in Galaxy Pairs
Jiwon Chung, Joon Hyeop Lee, Hyunjin Jeong
We present novel insights into the interplay between tidal forces and star formation in interacting galaxies before their first pericentre passage. We investigate seven close pair…
The SAMI Galaxy Survey: impact of star formation and AGN feedback processes on the ionized gas velocity dispersion
Sree Oh, Matthew Colless, Stefania Barsanti +12
We investigate the influence of star formation and instantaneous AGN feedback processes on the ionized gas velocity dispersion in a sample of 1285 emission-line galaxies with stell…
