UBVI CCD Photometry of the Old Open Cluster NGC 1193
Jaemann Kyeong, Sang Chul Kim, David Hiriart +1
We present UBVI photometry of the old open cluster NGC 1193. Color-magnitude diagrams (CMDs) of this cluster show a well defined main sequence and a sparse red giant branch. For th…
The WEBT Campaign on the Intermediate BL Lac Object 3C66A in 2007-2008
M. Boettcher, K. Fultz
Prompted by a high optical state in September 2007, the Whole Earth Blazar Telescope (WEBT) consortium organized an intensive optical, near-IR (JHK) and radio observing campaign on…
Multifrequency monitoring of the blazar 0716+714 during the GASP-WEBT-AGILE campaign of 2007
M. Villata, C. M. Raiteri, V. M. Larionov +5
Since the CGRO operation in 1991-2000, one of the primary unresolved questions about the blazar gamma-ray emission has been its possible correlation with the low-energy (in particu…
Molecular Hydrogen Kinematics in Cepheus A
David Hiriart, Luis Salas, Irene Cruz-Gonzalez
We present the radial velocity structure of the molecular hydrogen outflows associated to the star forming region Cepheus A. This structure is derived from doppler shift of the H_2…
