The Role of Environment in Shaping the Assembly Timelines of Massive Quiescent Galaxies at Cosmic Noon
JWST observations of massive quiescent galaxies (MQGs) at $z\sim2$ have revealed diverse star formation histories (SFHs).The physical and chemical structure of TMC-1. The spatial distribution and excitation conditions of carbon, oxygen, and sulfur bearing species: Depletion of CO and CS
We present a detailed study of the physical and chemical structure of TMC-1 from the observed spatial distribution of HC3N, NNH+, CN, and their isotopologues, the O-bearing species C18O, C17O…Galactic Morpholography: Linking present-day galaxy compactness to assembly history and relic formation in the COLIBRE simulations
Compactness is widely used to identify candidate relic galaxies, the largely untouched survivors of the first compact massive galaxies.Nova shells in 3D: I. A catalog of integral field spectroscopic observations
Classical novae eject material during thermonuclear eruptions on accreting white dwarfs, forming expanding shells whose structures and kinematics provide insights into the eruption mechanism and…Uncovering the origin of complex velocity distributions in edge-on disc galaxies
Stellar line-of-sight velocity distributions are a powerful tool for studying galaxy kinematics and formation history, with multiple-peaked LOSVDs often indicating the presence of complex kinematic…Constrain the Size of Broad Line Region in NGC 1068 Using Sub-millimeter Excess
Constraining the size of broad-line region (BLR) close to the accretion disk in active galactic nuclei (AGNs) is key to understand the central engine and evolution of AGN.The ringing Large Magellanic Cloud: evidence for a recent dwarf-dwarf collision
Galaxy interactions are ubiquitous in the Universe and represent a primary pathway for galaxy growth.IRAC-Excess Galaxies in the NIRSpec Wide Survey: physical properties of bright EELGs at $z\sim7$ and implications for Reionization
We present an analysis of 23 Spitzer/IRAC excess galaxies at $5.66 < z < 7.64$, observed as part of the NIRSpec Wide GTO survey.The contact frontier in Galactic civilization networks: radial structure and the Galactic habitable zone
The probability of interstellar contact depends not only on the abundance of technological civilizations but also on their spatial connectivity.A Parsec-Scale Transient High-Frequency-Peaked Radio Source in the Very Large Array Sky Survey Brightening and Fading over a Decadal Timescale
A subset of active galactic nuclei (AGN) manifests as compact radio sources with peaked radio spectra, commonly referred to as peaked-spectrum (PS) sources.A Step-Like Transition Underlying the Life and Death of Galaxies
How galaxies stop forming stars is a complex and central problem in astrophysics.Can bosenovae deplete the galactic dark matter?
No: neither through the bosenovae of gravitational atoms formed around stars and compact objects, nor through those of boson stars formed in the galactic dark-matter halo.Binary-lens amplification of starlight: from magnification flares to quasi-periodic tracking of orbital evolution
Supermassive black hole binaries (SMBHB) are expected at the center of galaxies as a result of galaxy mergers.A Parsec-scale Circumstellar Shell Around VX Sgr: Mass Loss and RSG/TŻO Nature
A thin, arc-shaped shell is discovered surrounding VX Sagittarii (VX Sgr), the largest known CSM shell around an RSG at a scale $r\sim0.59\,\mathrm{pc}$.JWST Observations of RR Lyrae in Leo P
We analyze co-spatial HST/ACS and JWST/NIRCam time-series photometric observations of RR Lyrae in the low-metallicity dwarf galaxy Leo P. This study provides a new opportunity to explore the…The impact of nonlinear Landau damping on cosmic ray streaming and the role of external turbulence
Cosmic rays (CRs) streaming faster than the Alfvén speed generate Alfvén waves that scatter them.A Vision for Little Red Dots in the Low-Redshift Universe with ALMA2040
The discovery of Little Red Dots (LRDs) at high redshifts with JWST has revealed a previously unknown phase of black-hole growth.The Impact of High-Mass Clusters on the Binary Black Hole Merger Rate over Cosmic Time
We present a cosmological calculation of the binary black hole merger rate from dense star clusters, using a $\texttt{Cluster Monte Carlo}$ ($\texttt{CMC}$) model grid spanning the full observed…Efficient numerical evolution of self-gravitating systems with dark-matter-baryon scattering
We present a fast algorithm to numerically evolve a spherically symmetric system consisting of dark matter and gas, including dark-matter-baryon scattering.CoRGI in MaNGA - II. NGC 5717: cold-gas accretion and disk growth in a BGG
Large-scale stellar counter-rotation, in which two coplanar stellar components rotate in opposite directions, is usually interpreted as a signature of external gas accretion.
