An Ammonia Spectral Map of the L1495-B218 Filaments in the Taurus Molecular Cloud: II CCS & HCN Chemistry and Three Modes of Star Formation in the Filaments
Young Min Seo, Liton Majumdar, Paul F. Goldsmith +22
We present deep CCS and HCN observations of the L1495-B218 filaments in the Taurus molecular cloud obtained using the K-band focal plane array on the 100m Green Bank Telescope.…
Relativistic Jets in Active Galactic Nuclei
Roger Blandford, David Meier, Anthony Readhead
The nuclei of most normal galaxies contain supermassive black holes, which can accrete gas through a disk and become active. These Active Galactic Nuclei, AGN, can form jets which…
PASIPHAE: A high-Galactic-latitude, high-accuracy optopolarimetric survey
Konstantinos Tassis, Anamparambu N. Ramaprakash, Anthony C. S. Readhead +13
PASIPHAE (the Polar-Areas Stellar Imaging in Polarization High-Accuracy Experiment) is an optopolarimetric survey aiming to measure the linear polarization from millions of stars,…
The C-Band All-Sky Survey (C-BASS): Constraining diffuse Galactic radio emission in the North Celestial Pole region
C. Dickinson, A. Barr, H. C. Chiang +17
The C-Band All-Sky Survey C-BASS is a high-sensitivity all-sky radio survey at an angular resolution of 45 arcmin and a frequency of 4.7 GHz. We present a total intensity 4.7 GHz m…
Constraining the limiting brightness temperature and Doppler factors for the largest sample of radio bright blazars
I. Liodakis, T. Hovatta, D. Huppenkothen +3
Relativistic effects dominate the emission of blazar jets complicating our understanding of their intrinsic properties. Although many methods have been proposed to account for them…
Demonstration of magnetic field tomography with starlight polarization towards a diffuse sightline of the ISM
Georgia V. Panopoulou, Konstantinos Tassis, Raphael Skalidis +7
The availability of large datasets with stellar distance and polarization information will enable a tomographic reconstruction of the (plane-of-the-sky-projected) interstellar magn…
The extreme HBL behaviour of Markarian 501 during 2012
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +276
A multiwavelength campaign was organized to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC,…
Multi-wavelength characterization of the blazar S5~0716+714 during an unprecedented outburst phase
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +187
The BL Lac object S5~0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC obs…
The C-Band All-Sky Survey (C-BASS): Design and capabilities
Michael E. Jones, Angela C. Taylor, Moumita Aich +23
The C-Band All-Sky Survey (C-BASS) is an all-sky full-polarisation survey at a frequency of 5 GHz, designed to provide complementary data to the all-sky surveys of WMAP and Planck,…
The State-of-Play of Anomalous Microwave Emission (AME) Research
Clive Dickinson, Y. Ali-Haïmoud, A. Barr +30
Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range -60 GHz. AME was first detected in 1996 and recogni…
