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…

SQuIGGLE: Radio AGN Found Predominantly in Young, Gas-rich Post-starburst Galaxies at z ~ 0.7

Vincenzo R. D'Onofrio, Justin S. Spilker, Krista L. Smith +13

The processes that rapidly quench massive galaxies and maintain their quiescence remain poorly understood. Substantial molecular gas reservoirs can survive this shutdown in post-st…

The DAWN JWST Archive: A spectroscopically-informed population study of the physical properties of galaxies at z>2

Rashmi Gottumukkala, Gabriel Brammer, Sune Toft +30

Charting the evolution of star-formation, stellar mass and dust build-up over cosmic time relies on the accurate characterisation of the stellar population properties of high redsh…

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…

DeepDive: Simultaneous Formation of Massive Quiescent Galaxies in High-Redshift Galaxy Overdensities

Takumi Kakimoto, Masayuki Tanaka, Kei Ito +20

We report on the spectroscopic confirmation of overdense regions of massive quiescent galaxies (QGs) in the early Universe with JWST/NIRSpec. Based on data from the DeepDive NIRSpe…

DeepDive: Tracing the early quenching pathways of massive quiescent galaxies at from their star-formation histories and chemical abundances

Massissilia L. Hamadouche, Katherine E. Whitaker, Francesco Valentino +21

We investigate the chemical abundances and star-formation histories (SFH) of ten massive () quiescent galaxies at usi…

There and back again? Neutral outflows in z~3.5 quiescent galaxies

Pengpei Zhu, Kei Ito, Francesco Valentino +16

Neutral gas outflows play a crucial role in the baryon cycle of galaxies, their properties provide key insights into the transition from star formation to quiescence. In this work,…

SQuIGGE: Buried star formation cannot explain the rapidly fading CO(2-1) luminosity in massive, post-starburst galaxies

David J. Setton, Justin S. Spilker, Rachel Bezanson +12

Observational and theoretical studies have long held that rapid gas consumption in starbursts is responsible for the formation of quiescent galaxies. However, studies of recently q…

Quenching Through Tidal Gas Removal: Molecular Gas and Star Formation in Tidal Tails of z ~ 0.7 Post-Starburst Galaxies

Vincenzo R. D'Onofrio, Justin S. Spilker, Rachel Bezanson +10

The active suppression of star formation in galaxies is critical in preventing the growth of overly massive systems and explaining the formation of present-day elliptical galaxies.…

DeepDive: A deep dive into the physics of the first massive quiescent galaxies in the Universe

K. Ito, F. Valentino, G. Brammer +26

We present the DeepDive program, in which we obtained deep JWST/NIRSpec G235M/F170LP spectra for ten primary massive () quiescent galaxies at $z\…

A merging pair of massive quiescent galaxies at in the Cosmic Vine

K. Ito, F. Valentino, M. Farcy +26

We report the spectroscopic confirmation of a merging pair of massive quiescent galaxies at . Using JWST observations, we confirm that the two galaxies lie at a projected s…

Gas outflows in two recently quenched galaxies at z = 4 and 7

F. Valentino, K. E. Heintz, G. Brammer +33

Outflows are a key element in the baryon cycle of galaxies, and their properties provide a fundamental test for our models of how star formation quenches in galaxies. Here we repor…

Different Formation Scenarios of Counter-rotating Stellar Disks in Nearby Galaxies

Min Bao, Yanmei Chen, Pengpei Zhu +7

Using the integral field unit (IFU) data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we select a sample of 101 galaxies with counter-rotating stellar d…
