Non-Axisymmetric Pillar Structures due to Embedded Stars in AGN Accretion Discs
Gravitationally unstable outer regions of AGN discs may host in situ formation of massive stars whose heating produces localized vertical "pillars" on the disc surface, in the same region that emits…An Extra-nuclear Water Maser in NGC 1106 Likely Driven By An AGN Shock: Implications for Maser-based Black Hole Mass Measurements
We present Very Large Array A-configuration ($0.13$'') 22 GHz spectral-line and continuum observations of the Swift-BAT detected Seyfert 2 galaxy, NGC 1106, aimed at localizing a water maser line…Collapsars Are Not Heavy $r$-Process Factories
Collapsar disks are proposed sources of $r$-process elements, but neutron-rich disk ejecta require gas to be both neutronized in the disk and ejected before accretion.The Galactic Center Reference Frame: A 30-Year Solution
Stellar orbits probe the metric of and mass around the Sgr A* massive black hole.AMICO galaxy clusters in KiDS-1000: Cosmological constraints from the two-point correlation function
In this paper we study the clustering properties of an optically identified photometric galaxy cluster catalogue from KiDS-1000.The SDSS-V Local Volume Mapper (LVM): Technical Overview
The Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM) is an ultra-wide integral field spectroscopic survey of the Milky Way, the Magellanic Clouds, and a sample of galaxies in the local…Tilt, warp, and dissipation flare in hydrodynamic disks around kicked compact objects
We study the dynamical response of a hydrodynamic disk to an impulsive kick imparted to a central massive object, focusing on the global properties of the material that remains gravitationally bound.The MAGE Project: Size Evolution and Disk Formation in Massive Galaxies at Cosmic Dawn
We investigate size evolution and disk formation with a new suite of eleven cosmological zoom-in simulations, Massive Assembly of Galaxies in the Early universe (MAGE), run with RAMSES at…NGC 3227 Blinks: An Extreme Changing-Look Event in a Seyfert Galaxy
We report a rapid optical changing-look event in the Seyfert galaxy NGC 3227: the optical continuum faded by more than 70% and broad H-beta emission nearly disappeared within weeks, before…Unveiling Accretion-Disk Reverberation Beneath BLR Contamination with TILDE
We present a Bayesian framework, Two-stage Inference for Light curve DEcomposition (TILDE), for mapping the accretion disk and the broad line region (BLR) from active galactic nuclei (AGN)…B-fields In STar-forming Region Observations (BISTRO): Technical Foundations for Quantitative 450/850 $μ$m JCMT SCUBA-2/POL-2 Polarimetry
We present five technical validations of SCUBA-2/POL-2 polarimetry on the James Clerk Maxwell Telescope at 450 and 850 $μ$m, using 174 archival fields in 69 molecular cloud regions and subsets…B-fields In STar-forming Region Observations (BISTRO): Dual-Wavelength Constraints on Size-Dependent Grain Alignment in Star-Forming Regions
We compared 450 and 850 $μ$m POL-2 observations from the James Clerk Maxwell Telescope at $12.6''$ resolution.simesh: A Python Framework for Quantitative Analysis of Native AMR Data from MPI-AMRVAC
Adaptive mesh refinement (AMR) is widely used in large-scale astrophysical simulations, but the resulting multilevel data are challenging to analyze quantitatively.Ballistic mixing: stellar mergers drive internal mixing in extremely massive stars, with implications for proto-globular cluster pollution
Extremely massive stars, with masses of $10^3$-$10^4$ M$_\odot$, have been proposed as potential sources of the chemical enrichment associated with multiple populations in globular clusters.Lasting mEMRIs: Signatures of Multiple Black Hole Extreme Mass Ratio Inspirals from AGN discs
Encounters of stellar-mass black holes (sBH) in active galactic nuclei discs naturally form mean-motion resonances of sBH pairs.FEAST: Spatially Resolved Star Formation History of the NGC 4485/NGC 4490 System and its Tidal Bridge from JWST/NIRCam Color Magnitude Diagrams
We present the spatially resolved star formation history (SFH) of the interacting, low-mass, gas-rich galaxy pair NGC 4485/NGC 4490, based on deep JWST/NIRCam imaging obtained as part of the FEAST…HETDEX [OII] galaxies at $z \le 0.48$: Growth of structures from power spectrum multipoles
We use the monopole and quadrupole power spectra of [\ion{O}{2}]-emitting galaxies in the HETDEX Public Data Release 1 to constrain the growth of cosmic structures at $z\le0.48$.Euclid Quick Data Release (Q1). Data processing for intracluster light measurements
The Euclid survey provides images with extraordinary potential for studies of the low-surface-brightness Universe, including intracluster light (ICL).Euclid Quick Data Release (Q1). The shape of cluster haloes revealed by intracluster light
Intracluster light (ICL) offers a luminous route for measuring the shapes and orientations of cluster haloes.Euclid Quick Data Release (Q1). A systematic study of the intracluster light fraction at 0.2 < z < 1.5
We present a homogeneous analysis of the intracluster light (ICL) in approximately 300 galaxy clusters spanning $0.2<z<1.5$, combining Sunyaev-Zeldovich-selected clusters from the South Pole…
