Using 21cm Absorption in Small Impact Parameter Galaxy-QSO Pairs to Probe Low-Redshift Damped and Sub-Damped Lyman-alpha System
Sanchayeeta Borthakur, Todd M. Tripp, Min S. Yun +4
To search for low-redshift damped Lyman-alpha (DLA) and sub-DLA quasar absorbers, we have conducted a 21cm absorption survey of radio-loud quasars at small impact parameters to for…
First Detection of the Zeeman Effect in the 36 GHz Class I methanol maser line with the EVLA
A. P. Sarma, E. Momjian
We report the first detection of the Zeeman effect in the 36 GHz Class I methanol maser line. The observations were carried out with 13 antennas of the EVLA toward the high mass st…
Constraints on the presence of water megamaser emission in z~2.5 ultraluminous infrared starburst galaxies
Jeff Wagg, Emmanuel Momjian
We present Expanded Very Large Array and Arecibo observations of two lensed submm galaxies at z~2.5, in order to search for redshifted 22.235 GHz water megamaser emission. Both SMM…
The covering factor of high redshift damped Lyman- systems
N. Kanekar, W. M. Lane, E. Momjian +2
We have used the Very Long Baseline Array to image 18 quasars with foreground damped Lyman- systems (DLAs) at 327, 610 or 1420 MHz, to measure the covering factor of each DL…
