SDSS-IV MaNGA: The [/Fe] of Early-Type Galaxies
Yiqing Liu
The mean stellar alpha-to-iron abundance ratio ([/Fe]) of a galaxy is an indicator of galactic star formation timescale. It is important for understanding the star formation his…
Observational constraints on dust disk sizes in tidally truncated protoplanetary disks in multiple systems in the Taurus region
C. F. Manara, M. Tazzari, F. Long +16
The impact of stellar multiplicity on the evolution of planet-forming disks is still the subject of debate. Here we present and analyze disk structures around ten multiple stellar…
The ACS Fornax Cluster Survey. III. Globular Cluster Specific Frequencies of Early-Type Galaxies
Yiqing Liu, Eric W. Peng, Andrés Jordán +4
The globular cluster (GC) specific frequency (), defined as the number of GCs per unit galactic luminosity, represents the efficiency of GC formation (and survival) compared t…
Virgo Redux: The Masses and Stellar Content of Nuclei in Early-Type Galaxies from Multi-Band Photometry and Spectroscopy
Chelsea Spengler, Patrick Côté, Joel Roediger +14
We present an analysis of 39 nuclei and their early-type hosts in the Virgo Cluster using ten broadband filters: F300W, F475W, F850LP, F160W, , and . We describe the…
The Influence of Environment on the Chemical Evolution in Low-mass Galaxies
Yiqing Liu, Luis C. Ho, Eric Peng
The mean alpha-to-iron abundance ratio ([/Fe]) of galaxies is sensitive to the chemical evolution processes at early time, and it is an indicator of star formation timescale ($τ…
The ACS Fornax Cluster Survey. XII. Diffuse Star Clusters in Early-type Galaxies
Yiqing Liu, Eric W. Peng, Sungsoon Lim +5
Diffuse star clusters (DSCs) are old and dynamically hot stellar systems that have lower surface brightness and more extended morphology than globular clusters (GCs). Using the ima…
Evidence for the rapid formation of low mass early-type galaxies in dense environments
Yiqing Liu, Eric W. Peng, John Blakeslee +6
We explore the environmental dependence of star formation timescales in low mass galaxies using the [/Fe] abundance ratio as an evolutionary clock. We present integrated [/Fe…
