Comparing Infrared & X-ray-selected Active Galactic Nuclei host galaxy star formation rates to the galaxy main sequence
A key method of exploring the relationship between active galactic nuclei (AGN) and their host galaxies is to determine the astrophysical properties of galaxies that host AGN, and compare them to…A blazar is a blazar is a blazar ... Comparing long-term varaibility properties of PKS 1510-089 and PKS 2155-304
Blazars are typically divided by spectral appearance; may that be strength of optical emission lines or the frequency of the synchrotron peak.Broad Line Regions behind a Haze II: A Three-dimensional Electron-scattering Model of the Broad Br$γ$ Line in NGC 3783
We investigate the broad Br$γ$ line in the type-1 active galactic nucleus NGC 3783 using three-dimensional Monte Carlo electron-scattering radiative transfer with SKIRT.Exploring Cosmic Rays from Gravity-Limited Acceleration at Supermassive Black Holes
We show that horizon-scale magnetic fields around supermassive black holes (SMBHs), only limited by gravity, yield a universal, model-independent ceiling on electromagnetic energy density.ExHaLe-jet: Modeling blazar jets with an extended hadro-leptonic radiation code
Blazars - active galaxies with the jet pointing at Earth - emit across all electromagnetic wavelengths.Isomer-resolved ion-molecule reaction kinetics of HCO+ and HOC+
The HCO$^+$/HOC$^+$ abundance ratio has been observed to vary significantly in different astrophysical environments, making it an important diagnostic tool for exploring the interstellar medium.Galaxy bias of radio AGN and star-forming galaxies from MIGHTEE and CMB lensing
Radio galaxies play a significant role in galaxy evolution through feedback mechanisms, making it important to characterize the environments in which they reside.A Hectospec Spectroscopic Census of Kinematic Members in the Orion Nebula Cluster
We present a comprehensive spectroscopic census of the Orion Nebula Cluster (ONC), based primarily on low-resolution optical spectroscopy obtained with MMT/Hectospec.Survey of Orion Disks with ALMA (SODA) IV: Millimeter variability of protoplanetary disks
Short-term millimeter-wavelength variability in Class II young stellar objects (YSOs) has been considered minimal, often dismissed as very rare in ALMA-based studies on short timescales.A precessing AGN with S-shaped morphology discovered in MALS
We present J1221$-$1354, a precessing AGN discovered in the MeerKAT Absorption Line Survey (MALS) using deep L-band (0.9--1.6\,GHz) radio data.Clustering of JWST LRDs. Implications for PBHs and other early-forming seeds
We use the observed abundance and spatial clustering of JWST little red dots (LRDs) over z = 4--8 to confront two formation scenarios: the standard picture in which LRDs form in virialized…Revisiting the Mass and Scale Dependence of the "Lensing is Low" Effect with DECADE
Galaxy-galaxy lensing (GGL) is a critical probe of cosmology and galaxy formation.Beyond the dust: JWST reveals extinction and ice content in local (U)LIRGs
We investigate the spatially resolved extinction and ice column densities in four nearby interacting (U)LIRGs using JWST/NIRSpec integral field spectroscopy (R$\sim$2700; 0.97--5.14 $μ$m).Beyond the Disc--Spheroid Dichotomy at $0.6 < z < 8.0$: Evidence for a Morphological Indeterminacy Regime from JWST
Galaxy morphology is a fundamental tracer of galaxy assembly, but its characterization becomes increasingly uncertain in the early Universe.Can Blue UV-Bright Galaxies Drive Reionization at Cosmic Dawn? An $M_{\rm UV}=-19.6$ Galaxy with $f_{\rm esc}\approx0.85$ at $z=9.244$
We revisit EBG-1, a gravitationally lensed galaxy at $z = 9.244$, using newly obtained deep (14 hr) JWST/NIRSpec G235M ($R \sim 1000$) spectroscopy.The evolution of 3C 306 in the galaxy cluster RXCJ1454.4+1622: linking spectral ageing, ICM conditions, and jet dynamics through MHD simulations
We present a methodology for analysing radio sources in galaxy clusters by combining multi-frequency radio observations, X-ray analysis of the intracluster medium (ICM), and three-dimensional…A DECADE of Giants: A catalog of 42,000 optically identified galaxy clusters from 13,000 $\mathrm{deg}^2$ of the sky
Galaxy clusters are sensitive to a rich variety of physics spanning a wide dynamic range, from microphysical to cosmological scales.Modeling Multi-band Active Galactic Nuclei Lightcurves Using an Self-supervised Attentive Neural Process Network
With the the Legacy Survey of Space and Time (LSST), observations of tens of millions of quasars are expected.Testing the inelastic dark matter interpretation of the LZ event with heavy-element experiments
We consider the inelastic dark matter interpretation of the recent 248 keV event observed by LZ and identify different experiments that could test it.Detecting and Identifying Supernovae in AGN Accretion Disks
Stars may become embedded in active galactic nucleus (AGN) accretion disks and eventually explode as supernovae (SNe), whose detection would provide direct evidence for the existence and evolution…
