A MUltiwavelength Study of ELAN Environments (AMUSE): The Impact of Dense Environment on Massive Dusty Star-Forming Galaxies at Cosmic Noon

Yu-Jan Wang, Chian-Chou Chen, Fabrizio Arrigoni Battaia +3

To understand how massive galaxies are influenced by their surroundings, we present new ALMA and NOEMA observations as part of A MUltiwavelength Study of ELAN Environments (AMUSE$^…

QSO MUSEUM III: the circumgalactic medium in Ly emission around 120 quasars covering the SDSS parameter space. Witnessing the instantaneous AGN feedback on halo scales

Jay González Lobos, Fabrizio Arrigoni Battaia, Aura Obreja +3

Recent surveys show that quasars are surrounded by Hydrogen Lyman- (Ly) glows with diverse emission levels and extents. These seem to depend on the activity of embedded…

The MUSE Ultra Deep Field: A 5 Mpc stretch of the z 4 cosmic web revealed in emission

Davide Tornotti, Michele Fumagalli, Matteo Fossati +7

We detect Ly emission from a ~5 Mpc-long (comoving) portion of the cosmic web hosting an overdensity () of 19 Ly emitters (LAEs) at within the MUSE…

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 physicall…

High-definition imaging of a filamentary connection between a close quasar pair at z=3

Davide Tornotti, Michele Fumagalli, Matteo Fossati +16

Filaments connecting halos are a long-standing prediction of cold dark matter theories. We present a detection of the cosmic web emission connecting two quasar-host galaxies at red…

MAMMOTH-Subaru. II. Diverse Populations of Circumgalactic Ly Nebulae at Cosmic Noon

Mingyu Li, Haibin Zhang, Zheng Cai +23

Circumgalactic Lyman-alpha (Ly) nebulae are gaseous halos around galaxies exhibiting luminous extended Ly emission. This work investigates Ly nebulae from deep imaging of…

The luminosity-area relation of quasars' Ly nebulae

Fabrizio Arrigoni Battaia, Aura Obreja, Tiago Costa +2

Cool (~K) gas is commonly observed around quasars as traced by extended Ly emission. These large-scale nebulae are usually studied using circularly averaged sur…

Inspiraling streams of enriched gas observed around a massive galaxy 11 billion years ago

Shiwu Zhang, Zheng Cai, Dandan Xu +19

Stars form in galaxies, from gas that has been accreted from the intergalactic medium. Simulations have shown that recycling of gas-the reaccretion of gas that was previously eject…

A Multiwavelength Study of ELAN Environments (AMUSE). Mass budget, satellites spin alignment and gas infall in a massive quasar host halo

Fabrizio Arrigoni Battaia, Chian-Chou Chen, Hau-Yu Baobab Liu +14

The systematic targeting of extended Ly emission around high-redshift quasars resulted in the discovery of rare and bright Enormous Ly Nebulae (ELANe) associated with multipl…

A Multiwavelength Study of ELAN Environments (AMUSE): Detection of a dusty star-forming galaxy within the enormous Lyman nebula at sheds light on its origin

Chian-Chou Chen, Fabrizio Arrigoni Battaia, Bjorn H. C. Emonts +2

We present ALMA observations on and around the radio-quiet quasar UM287 at . Together with a companion quasar, UM287 is believed to play a major role in powering the surrou…

The WISSH quasars project VII. Outflows and metals in the circumgalactic medium around the hyper-luminous z~3.6 quasar J1538+08

A. Travascio, L. Zappacosta, S. Cantalupo +11

During the last years, Ly nebulae have been routinely detected around high-z, radio-quiet quasars (RQQs) thanks to the advent of sensitive integral field spectrographs. Constrai…

The Stacked Lyman-Alpha Emission Profile from the Circum-Galactic Medium of z~2 Quasars

Fabrizio Arrigoni Battaia, Joseph F. Hennawi, Sebastiano Cantalupo +1

In the context of the FLASHLIGHT survey, we obtained deep narrow band images of 15 quasars with GMOS on Gemini-South in an effort to measure Ly emission from circum- an…
