Gathering Galaxy Distances in Abundance with Roman Wide-Area Data
John P. Blakeslee, Michele Cantiello, Michael J. Hudson +5
The extragalactic distance scale is fundamental to our understanding of astrophysics and cosmology. In recent years, the surface brightness fluctuation (SBF) method, applied in the…
Constraining quenching timescales in galaxy clusters by forward-modelling stellar ages and quiescent fractions in projected phase space
Andrew M. M. Reeves, Michael J. Hudson, Kyle A. Oman
We forward-model mass-weighted stellar ages (MWAs) and quiescent fractions in projected phase space (PPS), using data from the Sloan Digital Sky Survey, to jointly constrain an inf…
The shape of dark matter haloes: results from weak lensing in the Ultraviolet Near-Infrared Optical Northern Survey (UNIONS)
Bailey Robison, Michael J. Hudson, Jean-Charles Cuillandre +11
Cold dark matter haloes are expected to be triaxial, and so appear elliptical in projection. We use weak gravitational lensing from the Canada-France Imaging Survey (CFIS) componen…
Discovery of a new Local Group Dwarf Galaxy Candidate in UNIONS: Boötes V
Simon E. T. Smith, Jaclyn Jensen, Joel Roediger +12
We present the discovery of Boötes V, a new ultra-faint dwarf galaxy candidate. This satellite is detected as a resolved overdensity of stars during an ongoing search for new Local…
Star formation characteristics of CNN-identified post-mergers in the Ultraviolet Near Infrared Optical Northern Survey (UNIONS)
Robert W. Bickley, Sara L. Ellison, David R. Patton +3
The importance of the post-merger epoch in galaxy evolution has been well-documented, but post-mergers are notoriously difficult to identify. While the features induced by mergers…
ShapePipe: a new shape measurement pipeline and weak-lensing application to UNIONS/CFIS data
Axel Guinot, Martin Kilbinger, Samuel Farrens +16
UNIONS is an ongoing collaboration that will provide the largest deep photometric survey of the Northern sky in four optical bands to date. As part of this collaboration, CFIS is t…
