Triangulum II: a very metal-poor and dynamically hot stellar system
Nicolas F. Martin, Rodrigo A. Ibata, Michelle L. M. Collins +7
We present a study of the recently discovered compact stellar system Triangulum II. From observations conducted with the DEIMOS spectrograph on Keck II, we obtained spectra for 13…
Stellar masses and star formation rates of lensed dusty star-forming galaxies from the SPT survey
Jingzhe Ma, Anthony H. Gonzalez, J. S. Spilker +18
To understand cosmic mass assembly in the Universe at early epochs, we primarily rely on measurements of stellar mass and star formation rate of distant galaxies. In this paper, we…
POLARBEAR Constraints on Cosmic Birefringence and Primordial Magnetic Fields
POLARBEAR Collaboration, Peter A. R. Ade, Kam Arnold +84
We constrain anisotropic cosmic birefringence using four-point correlations of even-parity -mode and odd-parity -mode polarization in the cosmic microwave background measurem…
An Extreme Starburst in Close Proximity to the Central Galaxy of a Rich Galaxy Cluster at z=1.7
Tracy Webb, Allison Noble, Andrew DeGroot +19
We have discovered an optically rich galaxy cluster at z=1.7089 with star formation occurring in close proximity to the central galaxy. The system, SpARCS104922.6+564032.5, was det…
The Spatially-Resolved Star Formation History of the M31 Outer Disc
Edouard J. Bernard, Annette M. N. Ferguson, Scott C. Chapman +4
We present deep Hubble Space Telescope Advanced Camera for Surveys observations of the stellar populations in two fields lying at 20 and 23 kpc from the centre of M31 along the sou…
Early Science with the Large Millimeter Telescope: Observations of dust continuum and CO emission lines of cluster-lensed submillimetre galaxies at z=2.0-4.7
J. A. Zavala, M. S. Yun, I. Aretxaga +19
We present Early Science observations with the Large Millimeter Telescope, AzTEC 1.1 mm continuum images and wide bandwidth spectra (73-111 GHz) acquired with the Redshift Search R…
