Structure of bright 2MASS galaxies: 2D fits to the K-S-band surface brightness profiles
2MASS K-S-band surface brightness profiles
2014/12/24
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for obtaining a detailed understanding of the galaxies populating our local ...
The 2Mass Color-magnitude Diagram of the Center of the Sagittarius Dwarf Galaxy: Photometric Measurements of a Surprisingly High Mean Metallicity
abundances stellar
2014/12/23
We present the Two Micron All Sky Survey (2MASS) (JW22;K, K) color-magnitude diagram for the region within 1◦ of the center of the Sagittarius dwarf spheroidal galaxy. Using the slope of the ...
A Search for High Proper Motion T Dwarfs with Pan-STARRS1 + 2MASS + WISE
Search Proper Motion Dwarfs
2011/10/13
We have searched ~8200 sq. degs for high proper motion (~0.5-2.7"/year) T dwarfs by combining first-epoch data from the Pan-STARRS1 (PS1) 3-Pi Survey, the 2MASS All-Sky Point Source Catalog, and the W...
Open clusters in 2MASS photometry - I. Structural and basic astrophysical parameters
associations general – infrared galaxies – astronomical databases
2011/10/21
The main goal of our project is to obtain a complete picture of individual open clusters from homogeneous data and then search for correlations between their astrophysical parameters. The near-infrare...
We report the discovery of a serious bias in galaxy photometry reported in the 2MASS Extended Source Catalog (Jarrett et al. 2000). Due to an undetermined flaw in the 2MASS surface photometry routines...
