- C. Brogan, L. M. Peréz, K. Tatematsu
- Physics, Geology
- 14 July 2015
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations from the 2014 Long Baseline Campaign in dust continuum and spectral line emission from the HL Tau region. The continuum…
High-resolution studies of radio sources in the Hubble Deep and Flanking Fields
- T. Muxlow, A. Richards, R. Windhorst
- Physics
- 31 January 2005
18 days of MERLIN data and 42 h of A-array VLA data at 1.4 GHz have been combined to image a 10-arcmin field centred on the Hubble Deep Field (HDF). This area also includes the Hubble Flanking Fields…

QUASI-PERIODIC FORMALDEHYDE MASER FLARES IN THE MASSIVE PROTOSTELLAR OBJECT IRAS 18566+0408
We report results of an extensive observational campaign of the 6 cm formaldehyde maser in the young massive stellar object IRAS 18566+0408 (G37.55+0.20) conducted from 2002 to 2009. Using the…

- C. Brogan, W. Goss, M. Claussen
- Physics
- 13 May 2013
We present a comprehensive view of the W51B H ii region complex and the W51C supernova remnant (SNR) using new radio observations from the VLA, VLBA, MERLIN, JCMT, and CSO along with archival data…
