Submillimeter galaxy overdensities around physically associated quasar pairs
Eileen Herwig, Fabrizio Arrigoni Battaia, Chian-Chou Chen +4
A commonly employed method to detect protoclusters in the young universe is the search for overdensities of massive star forming galaxies, such as submillimeter galaxies (SMGs), ar…

A candidate quadruple AGN system at
Eileen Herwig, Fabrizio Arrigoni Battaia, Eduardo Bañados +1
Multiple galaxies hosting active galactic nuclei (AGNs) at kiloparsec separation from each other are exceedingly rare, and in fact, only one quadruple AGN is known so far. These ex…

QSO MUSEUM II: Search for extended Ly emission around eight quasar pairs
Eileen Herwig, Fabrizio Arrigoni Battaia, Jay González Lobos +7
Extended Ly emission is routinely found around single quasars (QSO) across cosmic time. However, few studies have investigated how such emission changes in fields with physical…
