Inside-Out vs. Outside-In Quenching of MaNGA Galaxies: Dependence on Stellar Mass and Environment
Zi-Hua Ho, Lihwai Lin, Hung-Yu Jian +6
Galaxy quenching, the cessation of star formation, can proceed in spatially distinct ways, commonly described as inside-out or outside-in. However, the inferred quenching pattern d…
The ALMaQUEST Survey XVII: Unveiling Multiple Quenching Pathways in Green Valley Galaxies via Molecular Gas and Quenching Timescale Analyses
Lihwai Lin, Po-Feng Wu, Mallory D. Thorp +6
Statistically, green valley (GV) galaxies exhibit lower molecular gas fractions () and reduced star formation efficiency (SFE) compared to star-forming galaxies. However,…
Catalogs of optically-selected clusters and photometric luminous red galaxies from the Hyper Suprime-Cam Subaru Strategic Program final year dataset
Masamune Oguri, Yen-Ting Lin, Nobuhiro Okabe +9
We construct samples of optically-selected clusters and photometric luminous red galaxies (LRGs) from the Hyper Suprime-Cam Subaru Strategic Program final year dataset covering $\s…
Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds
Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23
We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a …
Physical properties of gas departing from circular rotation at 50 pc scales using the PHANGS-MUSE galaxies
Carlos López-Cobá, Lihwai Lin, Irene Cruz González +4
Noncircular motions have been observed across various spatial scales in disk galaxies, yet the physical properties of the gas involved in these motions remain poorly constrained. U…
SDSS-IV MaNGA: Spatial Evolution of Gas-Phase Metallicity Changes Induced by Galaxy Interactions
Hsi-An Pan, Lihwai Lin, Sebastian F. Sanchez +2
Gas-phase metallicity in interacting and merging galaxies offers key insights into their star formation processes and evolutionary histories. This study investigates the spatial ev…
