Coordinated multi-wavelength observations of Sgr A*
A. Eckart, R. Schoedel, F. K. Baganoff +26
We report on recent near-infrared (NIR) and X-ray observations of Sagittarius A* (Sgr A*), the electromagnetic manifestation of the ~4x10^6 solar masses super-massive black hole (S…
Very Large Array Observations of Galactic Center OH 1720 MHz Masers in Sagittarius A East and in the Circumnuclear Disk
L. O. Sjouwerman, Y. M. Pihlstrom
We present Very Large Array (VLA) radio interferometry observations of the 1720 MHz OH masers in the Galactic Center (GC). Most 1720 MHz OH masers arise in regions where the supern…
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…
Characteristics of EGRET Blazars in the VLBA Imaging and Polarimetry Survey (VIPS)
G. B. Taylor, S. E. Healey, J. F. Helmboldt +12
We examine the radio properties of EGRET-detected blazars observed as part of the VLBA Imaging and Polarimetry Survey (VIPS). VIPS has a flux limit roughly an order of magnitude be…
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…
