HST Pa Survey of the Galactic Center – Searching the missing young stellar populations within the Galactic Center
star formation process
2014/12/20
We present preliminary results of our \hst Pa$\alpha$ survey of the Galactic Center (\gc), which maps the central 0.65$\times$0.25 degrees around Sgr A*. This survey provides us with a more complete i...
The Progenitor Mass of SN 2011dh from Stellar Populations Analysis
Progenitor Mass Stellar Populations Analysis
2011/10/18
Using Hubble Space Telescope (HST) photometry, we characterize the age of the stellar association in the vicinity of supernova (SN) 2011dh and use it to infer the zero-age main sequence mass (M_{ZAMS}...

2011/10/13
We present Gran-Telescopio-Canarias/OSIRIS optical spectra of 4 of the most compact and massive early-type galaxies in the Groth Strip Survey at redshift z~1, with effective radii Reff=0.5-2.4 kpc and...

Searching function variations resolved stellar populations
2011/10/13
The initial mass function (IMF) succinctly characterizes a stellar population, provides a statistical measure of the end result of the star-formation process, and informs our under- standing of the st...
