Planck Cold Clumps in the λ Orionis Complex. I. Discovery of an Extremely Young Class 0 Protostellar Object and a Proto-brown Dwarf Candidate in the Bright-rimmed Clump PGCC G192.32-11.88
Sanhueza, Patricio; Kwon, Woojin; Lai, Shih-Ping +37 more
We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the λ Orionis complex in order to systematically investigate the effects of stellar feedback. In the particular case of PGCC G192.32-11.88, we discovered an extremely young Class 0 protostellar object (G192N) and a proto-brown dwar…

Liu, Tie; Wu, Yuefang; Meng, Fanyi +1 more
Ninety-six Planck cold dust clumps in the second quadrant were mapped with 12CO (1-0), 13CO (1-0), and C18O (1-0) lines at the 13.7 m telescope of Purple Mountain Observatory. 12CO (1-0) and 13CO (1-0) emissions were detected for all 96 clumps, while C18O (1-0) emissions were detect…
Discovery of γ-Ray Emission from the Radio-intermediate Quasar III Zw 2: Violent Jet Activity with Intraday γ-Ray Variability
Weng, Shan-Shan; Chen, Liang; Fan, Yi-Zhong +4 more
III Zw 2 is the prototype of radio-intermediate quasars. Although there is the evidence of possessing strong jet, significant γ-ray emission has not been reported before. In this work, we carry out a detailed analysis of the latest Fermi-LAT Pass 8 data. No significant γ-ray signal has been detected in the time-averaged 7-year Fermi-LAT data of II…
Maps of the Magellanic Clouds from Combined South Pole Telescope and PLANCK Data
Bleem, L. E.; Stark, A. A.; George, E. M. +39 more
We present maps of the Large and Small Magellanic Clouds from combined South Pole Telescope (SPT) and Planck data. The Planck satellite observes in nine bands, while the SPT data used in this work were taken with the three-band SPT-SZ camera, The SPT-SZ bands correspond closely to three of the nine Planck bands, namely those centered at 1.4, 2.1, …
The Swift AGN and Cluster Survey. II. Cluster Confirmation with SDSS Data
Bregman, Joel N.; Kochanek, Christopher S.; Dai, Xinyu +1 more
We study 203 (of 442) Swift AGN and Cluster Survey extended X-ray sources located in the SDSS DR8 footprint to search for galaxy over-densities in three-dimensional space using SDSS galaxy photometric redshifts and positions near the Swift cluster candidates. We find 104 Swift clusters with a >3σ galaxy over-density. The remaining targets are p…
