A DECADE of dwarfs: first detection of weak lensing around spectroscopically confirmed low-mass galaxies
Chun-Hao To, Chihway Chang, Dhayaa Anbajagane +35
We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECA…
Constraining the Stellar-to-Halo Mass Relation with Galaxy Clustering and Weak Lensing from DES Year 3 Data
G. Zacharegkas, C. Chang, J. Prat +100
We develop a framework to study the relation between the stellar mass of a galaxy and the total mass of its host dark matter halo using galaxy clustering and galaxy-galaxy lensing…
The Hierarchical Growth of Bright Central Galaxies and Intracluster Light as Traced by the Magnitude Gap
Jesse B. Golden-Marx, Y. Zhang, R. L. C. Ogando +48
Using a sample of 2800 galaxy clusters identified in the Dark Energy Survey across the redshift range , we characterize the hierarchical assembly of Bright Central…
Weak Gravitational Lensing around Low Surface Brightness Galaxies in the DES Year 3 Data
N. Chicoine, J. Prat, G. Zacharegkas +102
We present galaxy-galaxy lensing measurements using a sample of low surface brightness galaxies (LSBGs) drawn from the Dark Energy Survey Year 3 (Y3) data as lenses. LSBGs are diff…
Cosmological shocks around galaxy clusters: A coherent investigation with DES, SPT & ACT
D. Anbajagane, C. Chang, E. J. Baxter +111
We search for signatures of cosmological shocks in gas pressure profiles of galaxy clusters using the cluster catalogs from three surveys: the Dark Energy Survey (DES) Year 3, the…
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…
A Sample of Dust Attenuation Laws for DES Supernova Host Galaxies
J. Duarte, S. González-Gaitán, A. Mourao +58
Type Ia supernovae (SNe Ia) are useful distance indicators in cosmology, provided their luminosity is standardized by applying empirical corrections based on light-curve properties…
Lessons Learned from the Two Largest Galaxy Morphological Classification Catalogues built by Convolutional Neural Networks
Ting-Yun Cheng, H. Domínguez Sánchez, J. Vega-Ferrero +54
We compare the two largest galaxy morphology catalogues, which separate early and late type galaxies at intermediate redshift. The two catalogues were built by applying supervised…
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…
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…
Is diffuse intracluster light a good tracer of the galaxy cluster matter distribution?
H. Sampaio-Santos, Y. Zhang, R. L. C. Ogando +64
We explore the relation between diffuse intracluster light (central galaxy included) and the galaxy cluster (baryonic and dark) matter distribution using a sample of 528 clusters a…
Distance biases in the estimation of the physical properties of Hi-GAL compact sources-I. Clump properties and the identification of high-mass star forming candidates
Adriano Baldeschi, Davide Elia, Sergio Molinari +8
The degradation of spatial resolution in star-forming regions observed at large distances ( kpc) with Herschel,can lead to estimates of the physical parameters of the de…
Constraining AGN triggering mechanisms through the clustering analysis of active black holes
M. Gatti, F. Shankar, V. Bouillot +4
The triggering mechanisms for Active Galactic Nuclei (AGN) are still debated. Some of the most popular ones include galaxy interactions (IT) and disk instabilities (DI). Using an a…
Physical properties of AGN host galaxies as a probe of SMBH feeding mechanisms
M. Gatti, A. Lamastra, N. Menci +2
Using an advanced semi analytic model (SAM) for galaxy formation, we have investigated the statistical effects of assuming two different mechanisms for triggering AGN activity on t…
Triggering Active Galactic Nuclei in Hierarchical Galaxy Formation: Disk instability vs. Interactions
N. Menci, M. Gatti, F. Fiore +1
Using a semi analytic model for galaxy formation we investigate the effects of Black Hole accretion triggered by disk instabilities (DI) in isolated galaxies on the evolution of AG…
