Period-Luminosity Relations Derived from the OGLE-III Fundamental Mode Cepheids
C. Ngeow, S. Kanbur, H. Neilson +2
In this Paper, we have derived Cepheid period-luminosity (P-L) relations for the Large Magellanic Cloud (LMC) fundamental mode Cepheids, based on the data released from OGLE-III. W…
Testing Mass Loss in Large Magellanic Cloud Cepheids using Infrared and Optical Observations
Hilding R. Neilson, Chow-Choong Ngeow, Shashi M. Kanbur +1
It has been claimed that Period-Luminosity relations derived from infrared observations of Large Magellanic Cloud (LMC) Cepheids are less dependent on the metallicity of the Cephei…
Galaxy clusters discovered with a Sunyaev-Zel'dovich effect survey
Z. Staniszewski, P. A. R. Ade, K. A. Aird +41
The South Pole Telescope (SPT) is conducting a Sunyaev-Zel'dovich (SZ) effect survey over large areas of the southern sky, searching for massive galaxy clusters to high redshift. I…
Modeling Mass-Loss and Infrared Excess in Large Magellanic Cloud Cepheids
Hilding R. Neilson, Chow-Choong Ngeow, Shashi M. Kanbur +1
The purpose of this preliminary work is to determine if Large Magellanic Cloud (LMC) Cepheids have stellar winds. If a Cepheid undergoes mass loss then at some distance from the st…
The Dark Energy Survey Data Management System
Joseph J. Mohr, Wayne Barkhouse, Cristina Beldica +17
The Dark Energy Survey collaboration will study cosmic acceleration with a 5000 deg2 griZY survey in the southern sky over 525 nights from 2011-2016. The DES data management (DESDM…
The Period-Luminosity Relation for the Large Magellanic Cloud Cepheids Derived from Spitzer Archival Data
C. Ngeow, S. Kanbur
Using Spitzer archival data from the SAGE (Surveying the Agents of a Galaxy's Evolution) program, we derive the Cepheid period-luminosity (P-L) relation at 3.6, 4.5, 5.8 and 8.0 mi…
