An Off-Nuclear Tidal Disruption Event Discovered At Late Times: The Case Of TDE 2023mfm
We present the discovery and analysis of the optically selected tidal disruption event (TDE) 2023mfm, which originates from a wandering massive black hole (MBH) in a massive ($\sim 10^{11}…MOCSS: Multi-Object Coronagraphy for JWST/NIRSpec Slitless Spectroscopy
We present an experimental JWST/NIRSpec observational method to obtain $R\gtrsim1000$ G140M/F100LP slitless spectroscopic observations.Snapshots of r-process production in the Milky Way disk
Stars enhanced in heavy neutron capture elements like europium (Eu) provide a window into the rarest and most exotic nucleosynthetic events.CHAMPS: Data Reduction and Detection of ~3300 Dusty Galaxies at 1.2 mm
We present the reduction and source catalogs for the \textit{COSMOS High-$z$ ALMA-MIRI Population Survey} (CHAMPS), the largest Atacama Large (Sub)Millimeter Array (ALMA) blank field survey to date…Constraining reionization with persistent homology: a novel summary statistic for wide-field Lyman-$α$ emitter observations
The spatial clustering of Lyman-$α$ emitters (LAEs) is one of the most promising observables for constraining reionization.MEGATRON: The Physical Origins of Steep UV Slopes at High Redshift
The ultraviolet (UV) spectral slope, $β$, serves as a fundamental probe of stellar population properties and interstellar medium conditions in galaxies.LMC-Perturbed LZ Dark Matter Landscape
The local dark matter (DM) velocity distribution is significantly altered by the gravitational impact of the Large Magellanic Cloud (LMC), which creates a high-velocity tail.How well do integral-of-motion distribution functions describe Milky Way-analogue halos?
We study the dark-matter phase space distribution of Milky Way-mass halos in the Auriga simulations, considering both hydrodynamic and dark-matter-only runs.CHANG-ES XLII: Cosmic-Ray Electron Transport and the Spatially Resolved Radio-SFR Relation in Edge-on Galaxies
Radio continuum emission traces star formation in galaxies, but cosmic-ray electron (CRE) propagation between the disk and halo complicates this connection.Barred Galaxies in MaNGA: Stellar Mass Dependence and Black Hole Growth
This study investigates the role of internal structures, such as stellar bars and active galactic nuclei (AGN), in shaping galaxy evolution using 7,408 galaxies (2,641 barred) from the SDSS-IV MaNGA…Evidence for an extended Galactic proton component beyond the cosmic-ray knee
The cosmic-ray (CR) \textit{knee} at a few petaelectronvolts (PeV) is commonly associated with the acceleration limit of Galactic protons.Synthesis of organo-phosphorous species in space: the reaction of P$^+$ with C$_2$H$_2$
Despite its low cosmic abundance, phosphorus is a bioessential element whose prebiotic availability and incorporation into biomolecules remain open questions.Constraining the galaxy-halo connection at $z>10$ using the neighbors of UV-bright galaxies
JWST has discovered an overabundance of UV-luminous galaxies compared to extrapolations from pre-JWST galaxy formation models.A Probabilistic Method for Estimating VLBI Jet-Component Ejection Epochs. Application to MOJAVE 15 GHz VLBA Kinematics
Ejection epochs of parsec-scale jet components in active galactic nuclei (AGN), tracked with Very Long Baseline Interferometry (VLBI), are commonly estimated by extrapolating fitted trajectories…Constraining the Light Curves of Magnified Stellar Events at z ~ 0.725
Extreme magnification by lensing galaxy clusters allows the detection of high-luminosity stars during cluster caustic transient events at cosmological distances.Tracing Winds through the Fog: A Comprehensive Survey of LMC's Galactic Outflows with ULLYSES
We investigate nearside stellar-driven outflows from the Large Magellanic Cloud (LMC) using UV absorption-line spectroscopy of 170 OB stars, complemented by HI 21-cm emission and H$_α$ emission.H-alpha Star Formation Rates of the SHIELD Dwarf Galaxies
The Survey of HI in Extremely Low-mass Dwarfs (SHIELD) galaxy sample is an HI-selected catalog of galaxies that occupy the extreme low-mass end of the HI mass function.The Physical Origins of Scatter in the Dust Attenuation Scaling Relation of Star-Forming Galaxies: Star--Dust Geometry
Characterising the physical drivers of dust attenuation in star-forming galaxies (SFGs) is essential for interpreting their spectral energy distributions and star formation histories.Constraints on Supermassive Black Hole Binaries from the Lack of Resolvable Sources in the NANOGrav 15-yr Dataset
Pulsar timing arrays (PTAs) have found evidence of a gravitational wave background (GWB) consistent with a population of supermassive black hole binaries (SMBHBs), but have not yet resolved a…Cool Embeddings: Predicting Galaxy Cluster Cooling Times in IllustrisTNG and TNG-Cluster with AstroCLIP
Foundation models trained on optical astronomical data have not previously been applied to X-ray cluster thermodynamics.
