Cold Gas Infall onto A Brightest Group Galaxy via A Gas-Rich Minor Merger
Ming-Yang Zhuang, Jinyi Shangguan, Yuan Bian +6
Dust and cold gas are not uncommon in nearby early-type galaxies (ETGs), and represent an important aspect of their evolution. However, their origin has been debated for decades. P…
Influence of Barlens on the Bulge Parameters in the 2D Image Decomposition
Xinyang Li, Zhao-Yu Li, Yang A. Li +2
Recent observations and simulations have shown that a buckled bar in the face-on view can be considered as a combination of a long flat bar and a short round barlens (corresponding…
From Non-Detection to Detection: Atacama Compact Array Mosaic Observations of Faint Extended [C I] Emission in NGC 7679
Tomonari Michiyama, Toshiki Saito, Kouichiro Nakanishi +8
We report the detection of [C I] -- emission in the nearby galaxy NGC 7679 using the Atacama Compact Array (ACA) of the Atacama Large Millimeter/submillimeter Array (…
The PSF Smoothing Effect on Concentration-Related Parameters of High Redshift Galaxies in HST and JWST
Jia-Hui Wang, Zhao-Yu Li, Ming-Yang Zhuang +2
We perform a comprehensive investigation of the PSF smoothing effect on the measurement of concentration-related parameters (, Gini, ) of high redshift galaxies in the H…
