UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey
Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
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…
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…
UNIONS: The impact of systematic errors on weak-lensing peak counts
Emma Ayçoberry, Virginia Ajani, Axel Guinot +6
UNIONS is an ongoing deep photometric multi-band survey of the Northern sky. As part of UNIONS, CFIS provides r-band data which we use to study weak-lensing peak counts for cosmolo…
Rubin-Euclid Derived Data Products: Initial Recommendations
Leanne P. Guy, Jean-Charles Cuillandre, Etienne Bachelet +117
This report is the result of a joint discussion between the Rubin and Euclid scientific communities. The work presented in this report was focused on designing and recommending an…
Strong Lensing Science Collaboration input to the on-sky commissioning of the Vera Rubin Observatory
Graham P. Smith, Timo Anguita, Simon Birrer +10
We present the Strong Lensing Science Collaboration's (SLSC) recommended observing targets for the science verification and science validation phases of commissioning. Our recommen…
Ram Pressure Candidates in UNIONS
Ian D. Roberts, Laura C. Parker, Stephen Gwyn +17
We present a search for disturbed, candidate ram pressure stripping galaxies across more than 50 spectroscopically selected SDSS groups and clusters. Forty-eight ram pressure candi…
First detection of the 448 GHz ortho-H2O line at high redshift: probing the structure of a starburst nucleus at z = 3.63
C. Yang, E. González-Alfonso, A. Omont +4
Submillimeter rotational lines of H2O are a powerful probe in warm gas regions of the ISM, tracing scales and structures ranging from kpc disks to the most compact and dust-obscure…
A highly-ionized region surrounding SN Refsdal revealed by MUSE
W. Karman, C. Grillo, I. Balestra +9
Supernova (SN) Refsdal is the first multiply-imaged, highly-magnified, and spatially-resolved SN ever observed. The SN exploded in a highly-magnified spiral galaxy at z=1.49 behind…
