2014/12/9
In my thesis, I research four consequences of satellite and dark matter halo interaction on galaxy formation. ^ First, I investigate detailed physical processes in interaction between satellites and d...
A Bayesian approach to the semi-analytic model of galaxy formation
Pure sciences Galaxy population Diverse data sources Galaxy evolution Galaxy formation
2014/12/9
It is believed that a wide range of physical processes conspire to shape the observed galaxy population but it remains unsure of their detailed interactions. The semi-analytic model (SAM) of galaxy fo...
Exploring The Scaling Laws Of Star Formation
Pure sciences Star formation Scaling laws Large scale stars Galaxy formation Molecular gas
2014/12/9
Despite the well-established global Schmidt-Kennicutt (S-K) law which already serves as an essential prescription for large scale star formation in modeling and simulating galaxy formation and evoluti...
ON THE FORMATION AND EVOLUTION OF EARLY-TYPE GALAXIES
early-type galaxies galaxy evolution high-redshift galaxies
2014/12/9
Galaxies in the local Universe are characterized by blue, star-forming disk galaxies, and red, massive early-type galaxies (ETGs) whose star-formation has been quenched early in the Universe's history...
Measures of Star Formation Rates within Galaxies: the Impact of Diffuse Stellar Populations

2014/12/9
Thanks to the {\it Spitzer Space Telescope}, the infrared (IR) emission have been better studied in the past decades, as well as its relations to star formation rates (SFR) and the calibrations of IR ...
Dusty Star Formation in Extreme Environments: Galaxies and Galaxy Clusters in the Distant Universe

2014/12/9
In this thesis, we present a comprehensive study of the dust-obscured star formation (SF) activity in galaxy clusters out to high redshift using infrared (IR) imaging. Using hundreds of galaxy cluster...
This thesis presents a study of two basic modes of deformation of a thin sheet: wrinkling and crumpling, viewed primarily in the context of an elastic sheet confined by capillary forces on a drop of l...
Swelling and Folding as Mechanisms of 3D Shape Formation in Thin Elastic Sheets

2014/11/20
We work with two different mechanisms to generate geometric frustration on thin elastic sheets; isotropic differential growth and folding. We describe how controlled growth and prescribing folding pat...
