Tran, Kim-Vy H., Saintonge, Amelie, Moustakas, John, Bai, Lei, Gonzalez, Anthony H., Holden, Bradford P., ...
To trace how dust-obscured star formation varies with environment, we compare the fraction of 24 micron sources in a super galaxy group to the field and a rich galaxy cluster at z~0.35. We draw on...
Evolution of the Rate and Mode of Star Formation in Galaxies since z=0.7 (2009)
Dressler, Alan, Oemler, Augustus, Gladders, Michael G., Bai, Lei, Rigby, Jane R., ...
We present the star formation rate (SFR) and starburst fraction (SBF) for a sample of field galaxies from the ICBS intermediate-redshift cluster survey. We use [O II] and Spitzer 24 micron fluxes to...
The infrared luminosity functions of rich clusters (2009)
Bai, Lei, Rieke, George H., Rieke, Marcia J., Christlein, Daniel, Zabludoff, Ann I.
The IR Luminosity Functions of Rich Clusters (2008)
Bai, Lei, Rieke, George H., Rieke, Marcia J., Christlein, Daniel, Zabludoff, Ann I.
We present MIPS observations of the cluster A3266. About 100 spectroscopic cluster members have been detected at 24 micron. The IR luminosity function in A3266 is very similar to that in the Coma...
The Late Stellar Assembly of Massive Cluster Galaxies Via Major Merging (2008)
Tran, Kim-Vy H., Moustakas, John, Gonzalez, Anthony H., Bai, Lei, Zaritsky, Dennis, Kautsch, Stefan J.
We present multi-wavelength observations of the brightest galaxies in four X-ray luminous groups at z~0.37 that will merge to form a cluster comparable in mass to Coma. Ordered by increasing stellar...
Marble, Andrew R., Eriksen, Kristoffer A., Impey, Chris D., Bai, Lei, Miller, Lance
The Lyman-alpha forest has opened a new redshift regime for cosmological investigation. At z > 2 it provides a unique probe of cosmic geometry and an independent constraint on dark energy that is not...
Search for IR Emission from Intracluster Dust in A2029 (2007)
Bai, Lei, Rieke, George H., Rieke, Marcia J.
We have searched for IR emission from the intracluster dust (ICD) in the galaxy cluster A2029. Weak signals of enhanced extended emission in the cluster are detected at both 24 and 70 micron....
IR observations of MS 1054-03: Star Formation and its Evolution in Rich Galaxy Clusters (2007)
Bai, Lei, Marcillac, Delphine, Rieke, George H., Rieke, Marcia J., Tran, Kim-Vy H., Hinz, Joannah L., ...
We study the infrared (IR) properties of galaxies in the cluster MS 1054-03 at z=0.83 by combining MIPS 24 micron data with spectra of more than 400 galaxies and a very deep K-band selected catalog....
Infrared Luminosity Function of the Coma Cluster (2005)
Bai, Lei, Rieke, George H., Rieke, Marcia J., Hinz, Joannah L., Kelly, Douglas M., Blaylock, Myra
Using mid-IR and optical data, we deduce the total infrared (IR) luminosities of galaxies in the Coma cluster and present their infrared luminosity function (LF). The shape of the overall Coma IR LF...
