A DECADE of Giants: A catalog of 42,000 optically identified galaxy clusters from 13,000 of the sky
D. Anbajagane, C. To, M. Gaido +44
Galaxy clusters are sensitive to a rich variety of physics spanning a wide dynamic range, from microphysical to cosmological scales. Optical datasets are efficient at identifying c…
Physics-guided discovery of dynamical dark-energy equations of state through iterative AI reasoning
Clecio R. Bom, Bernardo M. Fraga, Miguel A. Sabogal +3
Phenomenological model building has traditionally relied on human reasoning: equations are proposed from theoretical intuition, analogy, or empirical convenience, and only then tes…
SLSim: a strong lensing population simulation package
Narayan Khadka, Simon Birrer, Henry Best +45
Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multi…
Homogeneity scale in the local Universe: Model-independent estimate from S-PLUS iDR6 blue galaxies
Camila Franco, Felipe Avila, Armando Bernui +8
We present a model-independent estimate of the angular homogeneity scale in the local Universe by analysing data from the Southern Photometric Local Universe Survey (S-PLUS). Two c…
The role of supercluster filaments in shaping galaxy clusters
Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44
In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We in…
The Dark Energy Camera All Data Everywhere cosmic shear project V: Constraints on cosmology and astrophysics from 270 million galaxies across 13,000 deg of the sky
D. Anbajagane, C. Chang, A. Drlica-Wagner +78
We present constraints on models of cosmology and astrophysics using cosmic shear data vectors from three datasets: the northern and southern Galactic cap of the Dark Energy Camera…
A cosmology weakly dependent measurement of 2D Baryon Acoustic Oscillations scale from the Southern Photometric Local Universe Survey
U. Ribeiro, F. Avila, C. R. Bom +8
Baryon Acoustic Oscillations (BAO) provide a robust standard ruler for observational cosmology, enabling precise constraints on the expansion history of the Universe. We present a…
The DECADE cosmic shear project IV: cosmological constraints from 107 million galaxies across 5,400 deg of the sky
D. Anbajagane, C. Chang, A. Drlica-Wagner +72
We present cosmological constraints from the Dark Energy Camera All Data Everywhere (DECADE) cosmic shear analysis. This work uses shape measurements for 107 million galaxies measu…
The DECADE cosmic shear project II: photometric redshift calibration of the source galaxy sample
D. Anbajagane, A. Alarcon, R. Teixeira +50
We present the photometric redshift characterization and calibration for the Dark Energy Camera All Data Everywhere (DECADE) weak lensing dataset: a catalog of 107 million galaxies…
The DECADE cosmic shear project I: A new weak lensing shape catalog of 107 million galaxies
D. Anbajagane, C. Chang, Z. Zhang +51
We present the Dark Energy Camera All Data Everywhere (DECADE) weak lensing dataset: a catalog of 107 million galaxies observed by the Dark Energy Camera (DECam) in the northern Ga…
A dark standard siren measurement of the Hubble constant following LIGO/Virgo/KAGRA O4a and previous runs
C. R. Bom, V. Alfradique, A. Palmese +4
We present a new constraint on the Hubble constant () from the standard dark siren method using a sample of well-covered gravitational waves (GW) alerts reported during th…
A dark siren measurement of the Hubble constant using gravitational wave events from the first three LIGO/Virgo observing runs and DELVE
V. Alfradique, C. R. Bom, A. Palmese +17
The current and next observation seasons will detect hundreds of gravitational waves (GWs) from compact binary systems coalescence at cosmological distances. When combined with ind…
