A Pre-Protostellar Core in L1551
J. Swift, Wm. J. Welch, J. Di Francesco
Large field surveys of NH3, C2S, 13CO and C18O in the L1551 dark cloud have revealed a prolate, pre-protostellar molecular core (L1551-MC) in a relatively quiescent region to the n…
Quiescent Dense Gas in Protostellar Clusters: the Ophiuchus A Core
James Di Francesco, Philippe Andre, Philip C. Myers
We present combined BIMA interferometer and IRAM 30 m Telescope data of N2H+ 1-0 line emission across the nearby dense, star forming core Ophiuchus A (Oph A) at high linear resolut…
An Extinction Threshold for Protostellar Cores in Ophiuchus
Doug Johnstone, James Di Francesco, Helen Kirk
We have observed continuum emission at lambda = 850 microns over ~4 square degrees of the Ophiuchus star-forming cloud using SCUBA on the JCMT, producing a submillimetre continuum…
The Faintness of the 158 um [CII] Transition in the z=6.42 Quasar SDSS J1148+5251
Alberto D. Bolatto, James Di Francesco, Chris J. Willott
We report the non-detection of the [CII] 157.74 um transition in the z=6.42 quasar SDSS J1148+5251 after 37.5 hours of integration with the James Clerk Maxwell Telescope. This tran…
