Chemodynamic evidence of pristine gas accretion in the void galaxy VGS 12
Evgeniya Egorova, Kathryn Kreckel, Oleg Egorov +5
Accretion of metal-poor gas is expected to be an important channel of gas replenishment in galaxy evolution studies. However, observational evidence of this process is still relati…
Hierarchical structure of the cosmic web and galaxy properties
Mariana Jaber, Marius Peper, Wojciech A. Hellwing +2
Voids possess a very complex internal structure and dynamics. Using -body simulations we study the hierarchical nature of sub-structures present in the cosmic web (CW). We use t…
The Unusual Milky Way-Local Sheet System: Implications for Spin Strength and Alignment
M. A. Aragon-Calvo, Joseph Silk, Mark Neyrinck
The Milky Way and the Local Sheet form a peculiar galaxy system in terms of the unusually low velocity dispersion in our neighbourhood and the seemingly high mass of the Milky Way…
Self-supervised Learning with Physics-aware Neural Networks I: Galaxy Model Fitting
Miguel A. Aragon-Calvo
Estimating the parameters of a model describing a set of observations using a neural network is in general solved in a supervised way. In cases when we do not have access to the mo…
Dark Matter Halo Properties vs. Local Density and Cosmic Web Location
Tze Goh, Joel Primack, Christoph T. Lee +6
We study the effects of the local environmental density and the cosmic web environment (filaments, walls, and voids) on key properties of dark matter halos using the Bolshoi-Planck…
A Machine Learning Approach to Galaxy-LSS Classification I: Imprints on Halo Merger Trees
Jianan Hui, Miguel A. Aragon-Calvo, Xinping Cui +1
The cosmic web plays a major role in the formation and evolution of galaxies and defines, to a large extent, their properties. However, the relation between galaxies and environmen…
The Void Galaxy Survey: Star Formation Properties
B. Beygu, K. Kreckel, J. M. van der Hulst +5
We study the star formation properties of 59 void galaxies as part of the Void Galaxy Survey (VGS). Current star formation rates are derived from and recent star formatio…
A Comparative Study of Density Field Estimation for Galaxies: New Insights into the Evolution of Galaxies with Environment in COSMOS out to z~3
Behnam Darvish, Bahram Mobasher, David Sobral +2
It is well-known that galaxy environment has a fundamental effect in shaping its properties. We study the environmental effects on galaxy evolution, with an emphasis on the environ…
The Void Galaxy Survey: Morphology and Star Formation Properties of Void Galaxies
B. Beygu, K. Kreckel, J. M. van der Hulst +5
We present the structural and star formation properties of 59 void galaxies as part of the Void Galaxy Survey (VGS). Our aim is to study in detail the physical properties of these…
The Void Galaxy Survey: Galaxy Evolution and Gas Accretion in Voids
Kathryn Kreckel, Jacqueline H. van Gorkom, Burcu Beygu +4
Voids represent a unique environment for the study of galaxy evolution, as the lower density environment is expected to result in shorter merger histories and slower evolution of g…
