MWC349A and B Are Not Gravitationally Bound: New Evidence
P. M. Drew, V. Strelnitski, H. A. Smith +3
The age and evolutionary status of MWC349A, the unique emission line star with maser and laser radiation in hydrogen recombination lines, remain unknown because the spectrum of the…
Non-Equilibrium Populations of Hydrogen in High-Redshift Galaxies
Brian B. Pomerantz, Kayla Redmond, Vladimir Strelnitski
We investigate the possibility of maser amplification in hydrogen recombination lines from the galaxies of first generation, at z<~30. Combining analytical and computational approa…
A Tight Connection between Gamma-Ray Outbursts and Parsec-Scale Jet Activity in the Quasar 3C 454.3
Svetlana G. Jorstad, Alan P. Marscher, Paul S. Smith +42
We analyze the multifrequency behavior of the quasar 3C 454.3 during three prominent γ-ray outbursts: 2009 Autumn, 2010 Spring, and 2010 Autumn. The data reveal a repeating pattern…
The brightest gamma-ray flaring blazar in the sky: AGILE and multi-wavelength observations of 3C 454.3 during November 2010
S. Vercellone, E. Striani, V. Vittorini +84
Since 2005, the blazar 3C 454.3 has shown remarkable flaring activity at all frequencies, and during the last four years it has exhibited more than one gamma-ray flare per year, be…
First Interferometric Images of the 36 GHz Methanol Masers in the DR21 Complex
Vincent L. Fish, Talitha C. Muehlbrad, Preethi Pratap +4
Class I methanol masers are believed to be produced in the shock-excited environment around star-forming regions. Many authors have argued that the appearance of various subsets of…
H2O Masers and Supersonic Turbulence
V. Strelnitski, J. Alexander, S. Gezari +3
We use unpublished and published VLBI results to investigate the geometry and the statistical properties of the velocity field traced by H2O masers in five galactic regions of star…
