Gamma-ray Flaring Emission in Blazar OJ287 Located in the Jet >14 pc from the Black Hole
I. Agudo, S. G. Jorstad, A. P. Marscher +8
We combine the Fermi-LAT light curve of the BL Lacertae type blazar OJ287 with time-dependent multi-waveband flux and linear polarization observations and submilliarcsecond-scale p…
Gamma-ray emission region located in the parsec scale jet of OJ287
Ivan Agudo, Svetlana G. Jorstad, Alan P. Marscher +8
We report on the location of the gamma-ray emission region in flares of the BL Lacertae object OJ287 at >14pc from the central supermassive black hole. We employ data from multi-sp…
A Molecular Star Formation Law in the Atomic Gas Dominated Regime in Nearby Galaxies
Andreas Schruba, Adam K. Leroy, Fabian Walter +11
We use the IRAM HERACLES survey to study CO emission from 33 nearby spiral galaxies down to very low intensities. Using atomic hydrogen (HI) data, mostly from THINGS, we predict th…
On the Location of the Gamma-ray Emission in the 2008 Outburst in the BL Lacertae Object AO 0235+164 through Observations across the Electromagnetic Spectrum
Ivan Agudo, Alan P. Marscher, Svetlana G. Jorstad +38
We present observations of a major outburst at centimeter, millimeter, optical, X-ray, and gamma-ray wavelengths of the BL Lacertae object AO 0235+164. We analyze the timing of mul…
Molecular investigations of comets C/2002 X5 (Kudo-Fujikawa), C/2002 V1 (NEAT), and C/2006 P1 (McNaught) at small heliocentric distances
N. Biver, D. Bockelée-Morvan, P. Colom +4
We present unique spectroscopic radio observations of comets C/2002 X5 (Kudo-Fujikawa), C/2002 V1 (NEAT), and C/2006 P1 (McNaught), which came within $r_h ~ 0.2 AU of the Sun in 20…
A Constant Molecular Gas Depletion Time in Nearby Disk Galaxies
F. Bigiel, A. K. Leroy, F. Walter +8
We combine new sensitive, wide-field CO data from the HERACLES survey with ultraviolet and infrared data from GALEX and Spitzer to compare the surface densities of H2, Sigma_H2, an…
