EvoSignal: LLM-Guided Evolutionary Design of Modular Traffic Signal Control Programs

Leizhen Wang, Peibo Duan, Zhenlin Qin +5

Effective traffic signal control (TSC) requires policies that respond to changing traffic demand and network conditions while meeting different control objectives. However, adaptin…

From Feedback-Free Star Clusters to Little Red Dots via Compaction

Avishai Dekel, Dhruba Dutta Chowdhury, Sharon Lapiner +6

We address the origin of the Little Red Dots (LRDs) seen by JWST at cosmic morning () as compact stellar systems with over-massive black holes (BHs). We propose…

From FFB Starbursts at Cosmic Dawn to Quenching at Cosmic Morning: Hi-z Galaxy Bimodality

Avishai Dekel, Nir Mandelker, Zhaozhou Li +5

We propose a mass-dependent bimodality in the early evolution of galaxies. The massive track connects the super-bright galaxies at cosmic dawn () to the super-massive quiesc…

On the origin of compressive turbulence in protoclumps in high redshift disks

Omry Ginzburg, Avishai Dekel, Nir Mandelker +4

The giant, star forming clumps in gas-rich, high redshift disks are commonly assumed to form due to gravitational instabilities, in which protoclumps have a Toomre- parameter le…

Growth of Massive Black-Holes in FFB Galaxies at Cosmic Dawn

Avishai Dekel, Nicholas C. Stone, Dhruba Dutta Chowdhury +4

The scenario of feedback-free starbursts (FFB), which predicts excessively bright galaxies at cosmic dawn as observed using JWST, may provide a natural setting for black hole (BH)…

Radial Transport in High-Redshift Disk Galaxies Dominated by Inflowing Streams

Dhruba Dutta Chowdhury, Avishai Dekel, Nir Mandelker +2

We study the radial transport of cold gas within simulated disk galaxies at cosmic noon, aiming at distinguishing between disk instability and accretion along cold streams from the…

Monochromatic globular clusters as a critical test of formation models for the dark matter deficient galaxies NGC1052-DF2 and NGC1052-DF4

Pieter van Dokkum, Zili Shen, Aaron J. Romanowsky +8

It was recently proposed that the dark matter-deficient ultra-diffuse galaxies DF2 and DF4 in the NGC1052 group could be the products of a "bullet dwarf" collision between two gas-…

Sunyaev-Zel'dovich Signal from Quasar Hosts: Implications for Detection of Quasar Feedback

Dhruba Dutta Chowdhury, Suchetana Chatterjee

Several analytic and numerical studies have indicated that the interstellar medium of a quasar host galaxy heated by feedback can contribute to a substantial secondary signal in th…

Estimating the Sunyaev - Zel'dovich signal from quasar hosts using a Halo Occupation Distribution based approach

Dhruba Dutta Chowdhury

The Sunyaev-Zeldovich (SZ) effect is a spectral distortion in the Cosmic Microwave Background (CMB), caused due to up-scattering of CMB photons by high energy electron distribution…
