Excited-state OH Masers and Supernova Remnants
Ylva M. Pihlström, Vincent L. Fish, Loránt O. Sjouwerman +3
The collisionally pumped, ground-state 1720 MHz maser line of OH is widely recognized as a tracer for shocked regions and observed in star forming regions and supernova remnants. W…
Effelsberg Observations of Excited-State (6.0 GHz) OH in Supernova Remnants and W3(OH)
Vincent L. Fish, Loránt O. Sjouwerman, Ylva M. Pihlström
While masers in the 1720 MHz transition of OH are detected toward many supernova remnants (SNRs), no other OH transition is seen as a maser in SNRs. We present a search for masers…
Relationships between the HI 21-cm line strength, MgII equivalent width and metallicity in damped Lyman-alpha absorption systems
S. J. Curran, P. Tzanavaris, Y. M. Pihlstroem +1
We present the results of a survey for 21-cm absorption in four never previously searched damped Lyman-alpha absorption systems (DLAs) with the Westerbork Synthesis Radio Telescope…
Excited-state OH Mainline Masers in AU Geminorum and NML Cygni
Lorant O. Sjouwerman, Vincent L. Fish, Mark J. Claussen +2
Excited-state OH maser emission has previously been reported in the circumstellar envelopes of only two evolved stars: the Mira star AU Geminorum and the hypergiant NML Cygni. We p…
Stirring the Embers: High Sensitivity VLBI Observations of GRB030329
Y. M. Pihlström, G. B. Taylor, J. Granot +1
We present high sensitivity Very Long Baseline Interferometry (VLBI) observations 806 days after the gamma-ray burst of 2003 March 29 (GRB030329). The angular diameter of the radio…
