DES to HSC: Detecting low surface brightness galaxies in the Abell 194 cluster using transfer learning

H. Thuruthipilly, Junais, J. Koda +7

Low surface brightness galaxies (LSBGs) are important for understanding galaxy evolution and cosmological models. The upcoming large-scale surveys are expected to uncover a large n…

A hidden active galactic nucleus powering bright [O III] nebulae in a protocluster at revealed by JWST

M. Solimano, J. González-López, M. Aravena +48

Galaxy protoclusters are sites of rapid growth, with a high density of massive galaxies driving elevated rates of star formation and accretion onto supermassive black holes. Here,…

Effects of galaxy environment on merger fraction

W. J. Pearson, D. J. D. Santos, T. Goto +13

Aims. In this work, we intend to examine how environment influences the merger fraction, from the low density field environment to higher density groups and clusters. We also aim t…

Attenuation proxy hidden in surface brightness-colour diagrams. A new strategy for the LSST era

K. Małek, Junais, A. Pollo +22

Large future sky surveys, such as the LSST, will provide optical photometry for billions of objects. This paper aims to construct a proxy for the far ultraviolet attenuation (AFUVp…

A comparative study of the fundamental metallicity relation: the impact of methodology on its observed evolution

F. Pistis, A. Pollo, M. Figueira +10

We used 5487 star-forming galaxies at redshift z~0.63 extracted from the VIPERS and 143774 comparison galaxies in the local Universe from the GSWLC catalog. We employed two familie…
