Quenching in Cosmic Sheets: Tracing the Impact of Large Scale Structure Collapse on the Evolution of Dwarf Galaxies
Imad Pasha, Nir Mandelker, Frank C. van den Bosch +2
Dwarf galaxies are thought to quench primarily due to environmental processes most typically occurring in galaxy groups and clusters or around single, massive galaxies. However, at…
A giant shell of ionized gas discovered near M82 with the Dragonfly Spectral Line Mapper pathfinder
Deborah Lokhorst, Roberto Abraham, Imad Pasha +8
We present the discovery of a giant cloud of ionized gas in the field of the starbursting galaxy M82. Emission from the cloud is seen in H and [NII]6583 in data obtained thou…
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…
Brackett- as a Gold-standard Test of Star Formation Rates Derived from SED Fitting
Imad Pasha, Joel Leja, Pieter G. van Dokkum +2
Using a local reference sample of 21 galaxies, we compare observations of the 2.16 m Brackett- (Br) hydrogen recombination line with predictions from the Prospector Bay…
