A Nascent Tidal Dwarf Galaxy Forming within the Northern HI Streamer of M82
Imad Pasha, Deborah Lokhorst, Pieter G. van Dokkum +12
We identify a 600 pc-wide region of active star formation located within a tidal streamer of M82 via emission ( erg s cm), us…
A Method To Characterize the Wide-Angle Point Spread Function of Astronomical Images
Qing Liu, Roberto Abraham, Colleen Gilhuly +14
Uncertainty in the wide-angle Point Spread Function (PSF) at large angles (tens of arcseconds and beyond) is one of the dominant sources of error in a number of important quantitie…
Tidal Distortions in NGC1052-DF2 and NGC1052-DF4: Independent Evidence for a Lack of Dark Matter
Michael A. Keim, Pieter van Dokkum, Shany Danieli +11
Two ultra diffuse galaxies in the same group, NGC1052-DF2 and NGC1052-DF4, have been found to have little or no dark matter and to host unusually luminous globular cluster populati…
SITELLE Hα Imaging Spectroscopy of z~0.25 Clusters: Emission Line Galaxy Detection and Ionized Gas Offset in Abell 2390 & Abell 2465
Qing Liu, Howard Yee, Laurent Drissen +9
Environmental effects are crucial to the understanding of the evolution of galaxies in dense environments, such as galaxy clusters. Using the large field-of-view of SITELLE, the un…
