HI in HO: Hoag's object revisited
Noah Brosch, Ido Finkelman, Tom Oosterloo +2
We present new HI observations of Hoag's Object obtained with the Westerbork Synthesis Radio Telescope (WSRT). The data show that the luminous optical ring around the elliptical bo…
Polar Ring Galaxies in the Galaxy Zoo
Ido Finkelman, S. J. Jose G. Funes, Noah Brosch
We report observations of 16 candidate polar ring galaxies (PRGs) identified by the Galaxy Zoo project in the Sloan Digital Sky Survey (SDSS) database. Deep images of five galaxies…
Dust and Ionized Gas Association in E/S0 Galaxies with Dust Lanes: Clues to their Origin
Ido Finkelman, Noah Brosch, S. J. Jose G. Funes +3
We present results from an on-going programme to study the dust and ionized gas in E/S0 galaxies with dust lanes. Our data, together with results from previous studies of E/S0 gala…
MOA-2011-BLG-293Lb: A test of pure survey microlensing planet detections
J. C. Yee, Y. Shvartzvald, A. Gal-Yam +10
Because of the development of large-format, wide-field cameras, microlensing surveys are now able to monitor millions of stars with sufficient cadence to detect planets. These new…
Continuum removal in Hα extragalactic measurements
Oded Spector, Ido Finkelman, Noah Brosch
We point out an important source of error in measurements of extragalactic H-alpha emission and suggest ways to reduce it. The H-alpha line, used for estimating star formation rate…
Hoag's Object: Evidence for Cold Accretion onto an Elliptical Galaxy
Ido Finkelman, Alexei Moiseev, Noah Brosch +1
(Abridged) We present new photometric and spectroscopic observations of the famous Hoag's Object, a peculiar ring galaxy with a central roundish core. The nature of Hoag's Object i…
