The SPTpol Extended Cluster Survey
L. E. Bleem, S. Bocquet, B. Stalder +135
We describe the observations and resultant galaxy cluster catalog from the 2770 deg SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich…
Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in the SPTpol 100-Square-Degree Survey
N. Huang, L. E. Bleem, B. Stalder +74
We present a catalog of galaxy cluster candidates detected in 100 square degrees surveyed with the SPTpol receiver on the South Pole Telescope. The catalog contains 89 candidates d…
The Evolution of Luminous Red Nova AT 2017jfs in NGC 4470
A. Pastorello, T. -W. Chen, Y. -Z. Cai +43
We present the results of our photometric and spectroscopic follow-up of the intermediate-luminosity optical transient AT 2017jfs. At peak, the object reaches an absolute magnitude…
The tidal disruption event AT2017eqx: spectroscopic evolution from hydrogen rich to poor suggests an atmosphere and outflow
M. Nicholl, P. K. Blanchard, E. Berger +24
We present and analyse a new tidal disruption event (TDE), AT2017eqx at redshift z=0.1089, discovered by Pan-STARRS and ATLAS. The position of the transient is consistent with the…
Probing IGM accretion onto faint Lyα emitters at z~2.8
Fakhri S. Zahedy, Michael Rauch, Hsiao-Wen Chen +3
(abridged) Observing the signature of accretion from the intergalactic medium (IGM) onto galaxies at z~3 requires the detection of faint (L<<L*) galaxies embedded in a filamentary…
