LOB-Impact Benchmark: Emergent Market Impact in Generative Limit Order Book Models

George Nigmatulin, Valentin Mohl, Sascha Frey +6

Realistic market impact is essential for generative limit order book (LOB) models to serve as world models for trading agents. If a simulator misprices this mechanism, agents learn…

ALMA2040: The High-Redshift Circumgalactic Medium. Imaging the fueling and feedback of galaxies in the early universe

Kirsty M. Butler, Justin Spilker, Seiji Fujimoto +23

Galaxies do not form in isolation, but rather as part of a wider interconnected web mediated at their interface by an extended gaseous atmosphere - the Circum-Galactic Medium (CGM)…

Direct measures of black hole masses through cosmic time

Roberto Decarli, Sabine Thater, Ivan Delvecchio +16

Supermassive black holes (BHs) are thought to reside in all massive galaxies. They play a fundamental role in shaping galaxy evolution by suppressing star formation and halting the…

Constraining the density distribution of the cold Circumgalactic Medium of quasars at z>2 through Lya, HeII and Ha emission

Andrea Travascio, Sebastiano Cantalupo, Titouan Lazeyras +16

Extended Lya emission is routinely detected around high-redshift quasars, revealing large reservoirs of cool circumgalactic medium (CGM). Its resonant nature complicates interpreta…

Resolving the physics of Quasar Ly Nebulae (RePhyNe): II. The dense and clumpy CGM of Quasars at 3.5

Titouan Lazeyras, Sebastiano Cantalupo, Andrea Travascio +10

The small scale density distribution of the cold circumgalactic medium (CGM) plays a central role in galaxy evolution, yet it is still poorly understood. We provide new constraints…

Morphology, sizes, and scatter in a large sample of distant quiescent galaxies

G. Scarpe, F. Valentino, K. Ito +3

After quenching galaxies keep growing in size across time, as established in the literature up to cosmic noon. In this work, we assemble one of the largest and most comprehensive m…

Strong environmental AGN enhancement among DSFGs in z > 2 protoclusters

Monica Natalia Isla Llave, Fabio Vito, Alberto Traina +17

Galaxy protoclusters (PCs) at z > 2 are dense regions in which cold gas availability and elevated galaxy interaction rates trigger intense, often dust-obscured, star formation. The…

High-ionization coronal lines trace quasar-like activity in recently quenched galaxies at high redshift

F. Valentino, K. Ito, M. Farcy +31

We report the detection of the high-ionization line [NeV]3427 in the JWST/NIRSpec archival spectra of 6 massive quenched galaxies at , identified from a parent s…

CO(7-6) and [C I](2-1) survey in z > 6 quasars

Fuxiang Xu, Roberto Decarli, Ran Wang +13

High-redshift () quasars trace the earliest supermassive black holes and intense star formation, offering key laboratories for black hole-galaxy evolution at cosmic dawn…

The galaxy-halo connection and the dynamical evolution of a giant disc in a massive node of the Cosmic Web at z~3

G. Quadri, S. Cantalupo, C. Bacchini +9

Recent JWST observations revealed the surprising presence of a giant and massive disc galaxy in a Cosmic Web node at z. This galaxy, named the Big Wheel, has a size almost t…

The hydrodynamical response of cold circumgalactic clouds to quasar radiation

Nicolas Ledos, Sebastiano Cantalupo, Titouan Lazeyras +8

Recent simulations increasingly resolve the small-scale structure of the circumgalactic medium (CGM), but the dynamical impact of ionising radiation on its cold K component…

Resolving circumgalactic gas flows around a z3.6 quasar using MUSE and ALMA

M. Galbiati, A. Pensabene, S. Cantalupo +10

The formation and evolution of galaxies is regulated by the exchange of gas with the surrounding large-scale structures on circum- and intergalactic scales. Yet, little is known ab…

The ionised interstellar medium of DSFGs revealed by JWST/NIRSpec and ALMA: Super-solar metallicity, low ionisation parameters and, typical electron densities

Steven Gillman, Kei Ito, Francesco Valentino +25

We present a detailed study of near-infrared (2-4m) JWST/NIRSpec spectra of 48 high-redshift () galaxies detected with ALMA at . From a multi-wa…

Dynamical properties and star formation history of a low-mass quenched galaxy at Cosmic Noon

K. Ito, F. Valentino, W. M. Baker +12

We present the spectroscopic confirmation and in-depth analysis of AURORA-LQG1, a low-mass quiescent galaxy at with observed with…

A quiescent galaxy in a gas-rich cosmic web node at z~3

Weichen Wang, Sebastiano Cantalupo, Marta Galbiati +11

Recent JWST observations have unveiled a large number of quiescent galaxies at , bringing potential challenges to current galaxy formation models. Since star formation i…
