The TOP-SCOPE survey of Planck Galactic Cold Clumps: Survey overview and results of an exemplar source, PGCC G26.53+0.17
Tie Liu, Kee-Tae Kim, Mika Juvela +11
The low dust temperatures (<14 K) of Planck Galactic Cold Clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. TOP-SCOPE i…
Arp 202: a TDG formed in a parent's extended dark matter halo?
T. C. Scott, P. Lagos, S. Ramya +6
We report on H + [NII] imaging of the Arp 202 interacting pair and its tidal dwarf galaxy (TDG) candidate as well as a GMOS long slit spectrum from the TDG candidate, observed w…
Enhancing the H2O Megamaser Detection Rate Using Optical and Mid-infrared Photometry
C. Y. Kuo, A. Constantin, J. A. Braatz +8
Water megamasers from circumnuclear disks in galaxy centers provide the most accurate measurements of supermassive black hole masses and uniquely probe the sub-parsec accretion pro…
ELUCID V. Lighting dark matter halos with galaxies
Xiaohu Yang, Youcai Zhang, Huiyuan Wang +16
In a recent study, using the distribution of galaxies in the north galactic pole of SDSS DR7 region enclosed in a 500$\mpch$ box, we carried out our ELUCID simulation (Wang et al.…
Current stage of the ATCA follow-up for SPLASH
Hai-Hua Qiao, Andrew J. Walsh, Zhi-Qiang Shen
Four ground-state OH transitions were detected in emission, absorption and maser emission in the Southern Parkes Large-Area Survey in Hydroxyl (SPLASH). We re-observed these OH mas…
Revisiting LS I +61 303 with VLBI astrometry
Y. W. Wu, G. Torricelli-Ciamponi, M. Massi +4
We conducted multi-epoch VLBA phase reference observations of LS I +61 303 in order to study its precessing radio jet. Compared to similar observations in 2006, we find that the ob…
