Magnetic field measurement in TMC-1C using 22.3 GHz CCS Zeeman splitting
Atanu Koley, Nirupam Roy, Emmanuel Momjian +2
Measurement of magnetic fields in dense molecular clouds is essential for understanding the fragmentation process prior to star formation. Radio interferometric observations of CCS…
Long-term variability of Class I methanol masers in the high mass star forming region DR21(OH)
Nycole Wenner, A. P. Sarma, E. Momjian
High mass stars play an important role in the Interstellar Medium, but much remains to be known about their formation. Class I methanol masers may be unique tracers of an early sta…
A Curious Case of Circular Polarization in the 25 GHz Methanol Maser Line toward OMC-1
A. P. Sarma, E. Momjian
We report the detection of a circular polarization signature in the Stokes profile of a 25 GHz Class I CHOH maser toward the high mass star forming region OMC-1. Such a fea…
The Zeeman Effect in the 44 GHz Class I Methanol (CH3OH) Maser Line Toward DR21W
Emmanuel Momjian, Anuj P. Sarma
We report the detection of the Zeeman effect in the 44 GHz Class I methanol maser line toward the high mass star forming region DR21W. There are two prominent maser spots in DR21W…
The Zeeman Effect in the 44 GHz Class I Methanol Maser Line toward DR21(OH)
E. Momjian, A. P. Sarma
We report the detection of the Zeeman effect in the 44 GHz Class I methanol maser line toward the star forming region DR21(OH). In a 219 Jy/beam maser centered at an LSR velocity o…
Parsec-scale magnetic fields in Arp 220
James McBride, Timothy Robishaw, Carl Heiles +2
We present the first very-long-baseline interferometry (VLBI) detections of Zeeman splitting in another galaxy. We used Arecibo Observatory, the Green Bank Telescope, and the Very…
