In-orbit Calibrations of the Ultra-Violet Imaging Telescope
S. N. Tandon, Annapurni Subramaniam, V. Girish +22
The Ultra-Violet Imaging Telescope (UVIT) is one of the payloads in ASTROSAT, the first Indian Space Observatory. The UVIT instrument has two 375mm telescopes: one for the far-ultr…
In-orbit Performance of UVIT and First Results
S. N. Tandon, J. B. Hutchings, S. K. Ghosh +23
The performance of the ultraviolet telescope (UVIT) on-board ASTROSAT is reported. The performance in orbit is also compared with estimates made from the calibrations done on the g…
In-orbit Performance of UVIT on ASTROSAT
Annapurni Subramaniam, Shyam N. Tandon, John Hutchings +23
We present the in-orbit performance and the first results from the ultra-violet Imaging telescope (UVIT) on ASTROSAT. UVIT consists of two identical 38cm coaligned telescopes, one…
Red population of Abell 1314 : A Rest-Frame Narrowband Photometric Evolutionary Analysis
Yuvraj Harsha Sreedhar
Red sequence galaxies form with an intense burst of star formation in the early universe to evolve passively into massive, metal rich, old galaxies at z ~ 0. But Abell 1314 (z=0.03…
Comparative studies of Population Synthesis Models in the frame work of modified Strömgren filters
Yuvraj Harsha Sreedhar, Karl Rakos, Gerhard Hensler
Evolutionary models form a vital part of stellar population research to understand their evolution, but despite their long history of development, they often misrepresent and misin…
Ages and Metallicities of Cluster Galaxies in A779 using Modified Strömgren Photometry
Yuvraj Harsha Sreedhar, Andrew P. Odell, Karl D. Rakos +2
In the quest for the formation and evolution of galaxy clusters, Rakos and co-workers introduced a spectrophotometric method using the modified Strömgren photometry. But with the c…
