Magnetic Properties of Galactic Molecular Clouds
The earliest studies of molecular clouds (MCs) showed scaling relations between mass and radius M$\sim$R^s with exponent s $\approx$ 2, known as the third Larson relation.ReveaLLAGN 3: Revealing the Infrared Spectral Energy Distributions of Low Luminosity AGN
The spectral energy distributions of active galactic nuclei (AGN) provide valuable information on the emission mechanisms taking place in their inner regions.Unveiling the Origins of Local Group Galaxies with ELT-SHARP: An Overview of Science Cases
The $Λ$CDM paradigm successfully describes large-scale cosmic structure, yet tensions possibly persist on galactic and sub-galactic scales.SHARP(ening the) view of unresolved globular clusters in ultra diffuse galaxies
Ultra-Diffuse Galaxies (UDGs) challenge current galaxy formation models within the ΛCDM framework, particularly regarding their dark matter content and formation histories.Black Hole Seeds and Little Red Dots: Connecting Formation and Growth with a JWST Multi-Cycle Treasury Program
JWST has revealed an abundant population of faint active galactic nuclei and a new class of compact, high-redshift sources known as Little Red Dots (LRDs), whose physical nature remains debated…Probing Dark Matter-Electron Scattering with the Central Molecular Zone
The Central Molecular Zone, a dense and gas-rich region surrounding the Galactic Center, hosts numerous dense molecular gas cores that provide unique environments to probe dark matter interactions.The obscured nucleus of NGC3256 S. I. Anisotropic AGN near-IR radiation field traced by CO v=1-0 with JWST/NIRSpec
The southern nucleus of NGC3256, a nearby luminous infrared (IR) interacting system (d=40 Mpc; L(IR)=10^11.6 Lsun), hosts a deeply obscured low-luminosity active galactic nucleus (AGN) associated…Why a Multi-Cycle Treasury Program is Essential to Maximize JWST's Scientific Contributions to Galaxy Formation
The Genesis Initiative is an extragalactic community-wide effort to coordinate white papers in response to the STScI Multi-Cycle Treasury (MCT) concept call.AGN Archaeology: A Systematic Search for Fading AGN in MaNGA
Active galactic nuclei (AGN) vary on broad timescales, but are primarily thought to "flicker" on and off during episodes of high and low accretion.A multi-epoch VLBI study of compact symmetric objects as contaminants in the search for milli-lenses
The Lambda Cold Dark Matter model predicts a high abundance of low-mass dark matter halos, which can be probed through milliarcsecond-scale gravitational lensing (milli-lensing) of background…DOWSING, Dust Observations With SCUBA-2 In Nearby Galaxies: I. Dust in M81
We present a resolved far-infrared/sub-millimetre study of dust in the nearby spiral galaxy M81 using Herschel PACS/SPIRE and JCMT SCUBA-2 observations from 70 to $850\,μ\mathrm{m}$.The HST-Hyperion Survey: X-ray AGN Enhancement in the Hyperion Proto-supercluster
Dense environments can influence both galaxy evolution and supermassive black hole growth, but whether they enhance or suppress (or both) active galactic nuclei (AGN) activity at high redshift…The ALPINE-CRISTAL-JWST Survey: The Tully-Fisher Relation at $z = 4-6$
The Tully-Fisher relation provides a fundamental link between galaxy mass and their kinematics.On the importance of medium-resolution continuum spectroscopy for JWST's extragalactic legacy
We argue for a significant investment of JWST time into an extremely deep medium-resolution NIRSpec MSA survey targeting a large, representative sample of high-redshift $(z>1.5)$ galaxies…Feedback-Driven Star Formation and YSO Distribution around H II Regions Sh2-140 and Sh2-145
OB2 associations are ideal sites for studying various star-formation processes.Eddies that ride the flow: a model of turbulence with Richardson dispersion and anomalous dissipation
We construct a divergence-free velocity field $\mathbf{u}(\mathbf{x},t)$ on $\mathbb{T}^{n}$ that is a genuine function of position and carries both defining properties of turbulent transport…Detection of Differential Chromatic Refraction with LSST Camera data
The Earth's atmosphere acts like a prism, deflecting blue light towards the zenith more than red light.A Machine Learning Approach to Coupling Photoionization & Multi-Frequency Radiation Hydrodynamics
We use machine learning (ML) to couple photoionization microphysics to radiation hydrodynamic simulations of line-driven winds.Formamide formation on forsterite and Mg(OH)$_2\cdot$H$_2$O
Formamide formation in the Universe has been the subject of debate due to its importance as a precursor to amino acids and RNA.CosmicGrain: An On-the-fly Dust Physics Module
We present CosmicGrain, a dust physics module built on Gadget-4 that models explicit dust superparticles that experience resolved gas-dust drag and radiation pressure, undergo collisional heating…
