Timing the r-Process Enrichment of the Ultra-Faint Dwarf Galaxy Reticulum II
Joshua D. Simon, Thomas M. Brown, Burçin Mutlu-Pakdil +65
The ultra-faint dwarf galaxy Reticulum II (Ret II) exhibits a unique chemical evolution history, with 72 +10/-12% of its stars strongly enhanced in r-process elements. We present d…
Type Ia Supernova cosmology combining data from the mission and the Vera C. Rubin Observatory
A. Bailey, M. Vincenzi, D. Scolnic +4
The mission will provide first-of-its-kind coverage in the near-infrared over deep (three fields, 10-20 square degrees each) and wide (10000 square degrees) fi…
Mapping gas around massive galaxies: cross-correlation of DES Y3 galaxies and Compton--maps from SPT and Planck
J. Sánchez, Y. Omori, C. Chang +124
We cross-correlate positions of galaxies measured in data from the first three years of the Dark Energy Survey with Compton--maps generated using data from the South Pole Telesc…
Bump Morphology of the CMAGIC Diagram
L. Aldoroty, L. Wang, P. Hoeflich +38
We apply the color-magnitude intercept calibration method (CMAGIC) to the Nearby Supernova Factory SNe Ia spectrophotometric dataset. The currently existing CMAGIC parameters are t…
Dark Energy Survey Year 3 Results: Measurement of the Baryon Acoustic Oscillations with Three-dimensional Clustering
K. C. Chan, S. Avila, A. Carnero Rosell +66
The three-dimensional correlation function offers an effective way to summarize the correlation of the large-scale structure even for imaging galaxy surveys. We have applied the pr…
Mapping Variations of Redshift Distributions with Probability Integral Transforms
J. Myles, D. Gruen, A. Amon +66
We present a method for mapping variations between probability distribution functions and apply this method within the context of measuring galaxy redshift distributions from imagi…
Characterising the Intracluster Light over the Redshift Range in the DES-ACT Overlap
Jesse B. Golden-Marx, Y. Zhang, R. L. C. Ogando +66
We characterise the properties and evolution of Bright Central Galaxies (BCGs) and the surrounding intracluster light (ICL) in galaxy clusters identified in overlapping regions of…
Dark Energy Survey Year 3 Results: Redshift Calibration of the MagLim Lens Sample from the combination of SOMPZ and clustering and its impact on Cosmology
G. Giannini, A. Alarcon, M. Gatti +111
We present an alternative calibration of the MagLim lens sample redshift distributions from the Dark Energy Survey (DES) first three years of data (Y3). The new calibration is base…
The He I 10830 line as a probe of winds and accretion in young stars in Lupus and Upper Scorpius
J. Erkal, C. F. Manara, P. C. Schneider +6
The He I 1 micron line is a high excitation line which allows us to probe the innermost regions of protostellar disks, and to trace both accreting and outflowing material. We use X…
OzDES Reverberation Mapping Program: Mg II Lags and R-L relation
Zhefu Yu, Paul Martini, A. Penton +55
The correlation between the broad line region radius and continuum luminosity ( relation) of active galactic nuclei (AGN) is critical for single-epoch mass estimates of superm…
Concerning Colour: The Effect of Environment on Type Ia Supernova Colour in the Dark Energy Survey
L. Kelsey, M. Sullivan, P. Wiseman +67
Recent analyses have found intriguing correlations between the colour () of type Ia supernovae (SNe Ia) and the size of their 'mass-step', the relationship between SN Ia host ga…
A Probabilistic Autoencoder for Type Ia Supernovae Spectral Time Series
George Stein, Uros Seljak, Vanessa Bohm +37
We construct a physically-parameterized probabilistic autoencoder (PAE) to learn the intrinsic diversity of type Ia supernovae (SNe Ia) from a sparse set of spectral time series. T…
A galaxy-driven model of type Ia supernova luminosity variations
P. Wiseman, M. Vincenzi, M. Sullivan +59
Type Ia supernovae (SNe Ia) are used as standardisable candles to measure cosmological distances, but differences remain in their corrected luminosities which display a magnitude s…
