Factors Contributing to Attitudinal Gains in Introductory Astronomy Courses
Adam S. Trotter, Daniel E. Reichart, Aaron P. LaCluyzé +1
Most students do not enroll in introductory astronomy as part of their major; for many, it is the last science course they will ever take. Thus, it has great potential to shape stu…
Skynet Algorithm for Single-Dish Radio Mapping I: Contaminant-Cleaning, Mapping, and Photometering Small-Scale Structures
J. R. Martin, D. E. Reichart, D. A. Dutton +22
We present a single-dish mapping algorithm with a number of advantages over traditional techniques. (1) Our algorithm makes use of weighted modeling, instead of weighted averaging,…
Robust Chauvenet Outlier Rejection
M. P. Maples, D. E. Reichart, N. C. Konz +7
Sigma clipping is commonly used in astronomy for outlier rejection, but the number of standard deviations beyond which one should clip data from a sample ultimately depends on the…
Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
The fading of Cassiopeia A, and improved models for the absolute spectrum of primary radio calibration sources
A. S. Trotter, D. E. Reichart, R. E. Egger +20
Based on five years of observations with the 40-foot telescope at Green Bank Observatory (GBO), Reichart & Stephens (2000) found that the radio source Cassiopeia A had either faded…
GRB 141221A: gone is the wind
O. Bardho, B. Gendre, A. Rossi +7
GRB 141221A was observed from infrared to soft gamma-ray bands. Here, we investigate its properties, in light of the standard model. We find that the optical light curve of the aft…
The central engine of GRB 130831A and the energy breakdown of a relativistic explosion
M. De Pasquale, S. R. Oates, J. L. Racusin +37
Gamma-ray bursts (GRBs) are the most luminous explosions in the universe, yet the nature and physical properties of their energy sources are far from understood. Very important clu…
The warm, the excited, and the molecular gas: GRB 121024A shining through its star-forming galaxy
M. Friis, A. De Cia, T. Krühler +28
We present the first reported case of the simultaneous metallicity determination of a gamma-ray burst (GRB) host galaxy, from both afterglow absorption lines as well as strong emis…
GRB 120711A: an intense INTEGRAL burst with long-lasting soft gamma-ray emission and a powerful optical flash
A. Martin-Carrillo, L. Hanlon, M. Topinka +20
A long and intense gamma-ray burst (GRB) was detected by INTEGRAL on July 11 2012 with a duration of ~115s and fluence of 2.8x10^-4 erg cm^-2 in the 20 keV-8 MeV energy range. GRB…
PROMPT Observations of the Early-Time Optical Afterglow of GRB 060607A
M. Nysewander, D. E. Reichart, J. A. Crain +5
PROMPT (Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes) observed the early-time optical afterglow of GRB 060607A and obtained a densely sampled multiwavelength…
The Geometry of and Mass Accretion Rate through the Maser Accretion Disk in NGC 4258
J. R. Herrnstein, J. M. Moran, L. J. Greenhill +1
A maximum likelihood analysis of the NGC 4258 maser positions and velocities reveals a ~2 sigma deviation from Keplerian motion in the projected rotation curve of the high-velocity…
Water maser emission and the parsec-scale jet in NGC 3079
Adam S. Trotter, Lincoln J. Greenhill, James M. Moran +3
We have conducted VLBI observations of water maser and radio continuum emission in the nucleus of NGC 3079. The 22 GHz maser emission arises in compact clumps, distributed along an…
VLBA Imaging of the OH Maser in IIIZw35
A. S. Trotter, J. M. Moran, L. J. Greenhill +2
We present a parsec-scale image of the OH maser in the nucleus of the active galaxy IIIZw35, made using the Very Long Baseline Array at a wavelength of 18 cm. We detected two disti…
