Galaxy And Mass Assembly (GAMA): Active Galactic Nuclei in Pairs of Galaxies
Yjan A. Gordon, Matt S. Owers, Kevin A. Pimbblet +14
There exist conflicting observations on whether or not the environment of broad and narrow line AGN differ and this consequently questions the validity of the AGN unification model…
Galaxy And Mass Assembly (GAMA): The group HI mass as a function of halo mass
Ajay Dev, Simon P. Driver, Martin Meyer +11
We determine the atomic hydrogen (HI) to halo mass relation (HIHM) using Arecibo Legacy Fast ALFA survey HI data at the location of optically selected groups from the Galaxy and Ma…
Galaxy and Mass Assembly (GAMA): The Weak Environmental Dependence of Quasar Activity at 0.1<z<0.35
Clare F. Wethers, Nischal Acharya, Roberto De Propris +13
Understanding the connection between nuclear activity and galaxy environment remains critical in constraining models of galaxy evolution. By exploiting extensive catalogued data fr…
Galaxy and Mass Assembly (GAMA): Low-redshift Quasars and Inactive Galaxies Have Similar Neighbors
Maria B. Stone, Clare F. Wethers, Roberto de Propris +5
We explore the properties of galaxies in the proximity (within a 2 Mpc radius sphere) of Type I quasars at 0.1<z<0.35, to check whether and how an active galaxy influences th…
Galaxy And Mass Assembly (GAMA): The effect of galaxy group environment on active galactic nuclei
Yjan A. Gordon, Kevin A. Pimbblet, Matt S. Owers +9
In galaxy clusters, efficiently accreting active galactic nuclei (AGN) are preferentially located in the infall regions of the cluster projected phase-space, and are rarely found i…
Galaxy Spectra neural Network (GaSNet). II. Using Deep Learning for Spectral Classification and Redshift Predictions
Fucheng Zhong, Nicola R. Napolitano, Caroline Heneka +25
Large sky spectroscopic surveys have reached the scale of photometric surveys in terms of sample sizes and data complexity. These huge datasets require efficient, accurate, and fle…
