A census of Dark Energy Survey Year 3 redMaPPer galaxy clusters in a high exposure eROSITA All Sky Survey region
P. A. Giles, A. K. Romer, J. Pilling +64
We present the cross-match of galaxy clusters detected by redMaPPer using the first three years of Dark Energy Survey (DESY3RM) operations, and the first release of the eROSITA-All…
Data-driven Galaxy Population Prior for Photometric Redshifts
Nikolas Frediani, Daniel Gruen, Luca Tortorelli +1
Stage-IV cosmological surveys rely on well-characterised photometric redshift distributions for constraining cosmological models, yet the projected weak lensing requirements are ab…
On the Clustering Bias of Unresolved Gamma-Ray Sources
Bhashin A. Thakore, Marco Regis, Michela Negro +4
The Unresolved -Ray Background (UGRB) encodes the collective emission of source populations that are too faint to be detected individually, and its cross-correlation with tracer…
A Natural Telescope: Discovery of the Strongly Lensed Type II SN 2025mkn at
Cameron Lemon, Ariel Goobar, Joel Johansson +90
We present the discovery of SN 2025mkn, a gravitationally lensed Type II supernova. First detected as a blue transient in ZTF, 0.83 from a elliptical gala…
Multi-Tracer Cross-Correlations of the Unresolved -Ray Sky
B. Thakore, M. Regis, M. Negro +4
Our understanding of the -ray sky has greatly advanced, yet studying the unresolved -ray background (UGRB) can unveil the nature of the faintest -ray source populations in…
Discovery of SN 2025wny: a Strongly Gravitationally Lensed Superluminous Supernova at z = 2.01
Joel Johansson, Daniel A. Perley, Ariel Goobar +31
We present the discovery of SN 2025wny (ZTF25abnjznp/GOTO25gtq) and spectroscopic classification of this event as the first gravitationally lensed Type I superluminous supernovae (…
Impact of stellar population synthesis choices on forward modelling-based redshift distribution estimates
Luca Tortorelli, Jamie McCullough, Daniel Gruen
The forward modelling of galaxy surveys has recently gathered interest as one of the primary methods to achieve the required precision on the estimate of the redshift distributions…
The Dark Energy Survey Supernova Program: Cosmological Biases from Host Galaxy Mismatch of Type Ia Supernovae
H. Qu, M. Sako, M. Vincenzi +58
Redshift measurements, primarily obtained from host galaxies, are essential for inferring cosmological parameters from type Ia supernovae (SNe Ia). Matching SNe to host galaxies us…
The Dark Energy Survey Supernova Program: Corrections on photometry due to wavelength-dependent atmospheric effects
J. Lee, M. Acevedo, M. Sako +64
Wavelength-dependent atmospheric effects impact photometric supernova flux measurements for ground-based observations. We present corrections on supernova flux measurements from th…
Measuring Cosmological Parameters with Type Ia Supernovae in redMaGiC galaxies
R. Chen, D. Scolnic, E. Rozo +82
Current and future cosmological analyses with Type Ia Supernovae (SNe Ia) face three critical challenges: i) measuring redshifts from the supernova or its host galaxy; ii) classify…
Milky Way Satellite Census. IV. Constraints on Decaying Dark Matter from Observations of Milky Way Satellite Galaxies
S. Mau, E. O. Nadler, R. H. Wechsler +66
We use a recent census of the Milky Way (MW) satellite galaxy population to constrain the lifetime of particle dark matter (DM). We consider two-body decaying dark matter (DDM) in…
DeepZipper: A Novel Deep Learning Architecture for Lensed Supernovae Identification
Robert Morgan, B. Nord, K. Bechtol +48
Large-scale astronomical surveys have the potential to capture data on large numbers of strongly gravitationally lensed supernovae (LSNe). To facilitate timely analysis and spectro…
A Very Large (") Strong Gravitational Lens Selected with the Sunyaev-Zel'dovich Effect: PLCK G287.0+32.9 ( = 0.38)
Adi Zitrin, Stella Seitz, Anna Monna +7
Since galaxy clusters sit at the high-end of the mass function, the number of galaxy clusters both massive and concentrated enough to yield particularly large Einstein radii poses…
