How Little Red Dots Turn Blue: Evolution of Kelvin-Helmholtz Contracting Black Hole Envelopes and Observational Diagnostics
James Webb Space Telescope (JWST) observations have revealed compact, red-colored, broad-line emitters known as little red dots (LRDs), while a bluer counterpart population has been referred to as…Tracing small-scale structure formation through cosmic time with strong gravitational lensing: A case for a next-generation sub-millimetre/millimetre interferometer
The nature of dark matter and the growth of supermassive black holes (SMBHs) remain major open questions in modern astrophysics.Probing ordered magnetic fields in galaxies across cosmic time
Magnetic fields are dynamically important across many astronomical environments, yet their origin, strength, and evolution over cosmic time remain poorly understood.The Pristine survey XXIX. Data Release 2: Photometric metallicities for 15 millions stars down to $G\sim 20.5$
Tailored narrow-band photometric observations are an efficient way to measure the metallicity of Milky Way stars.HI rotation curves and mass-size relation for 568 galaxies from the Apertif Wide-area Extragalactic Survey
The extended HI rotation curves of galaxies are one of the most powerful tools for studying galaxy evolution and for testing different dark matter and modified gravity models.Wandering intermediate-mass black holes and off-nuclear tidal disruption events from early star clusters
Off-nuclear tidal disruption events (TDEs) reveal evidence for massive black holes outside galactic centers, but the origins of this wandering population remain uncertain.An Attenuation Bump at z=9.3: Probing Dust Diversity at Cosmic Dawn
We report the identification of a UV attenuation bump in the Black Pearl, a galaxy at a spectroscopic redshift of 9.3335 observed with JWST/NIRSpec as part of the ZENITH and EMBER surveys.A model for the ongoing subcluster interaction in Centaurus
Intracluster globular clusters (GCs) preserve the hierarchical and chemical history of galaxy cluster assembly.Has JWST Seen Everything? Hunting for "NIRCam-dark" Dusty Star-Forming Galaxies at $z \simeq 6 - 9$ with ALMA2040
JWST/NIRCam has recovered the stellar counterparts of many ALMA-detected, formerly HST-dark galaxies, yet ALMA has started identifying dusty star-forming galaxies (DSFGs) at $z>6$ that remain…ALMA2040: Understanding the Early Assembly of Galaxies - The Formation of Star-Forming Clumps and their Role in Shaping Galaxy Evolution
Astrophysics seeks to explain how galaxies form and evolve through the interplay of stars, gas, and dust.The dawn of the first galaxies
Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics.A Search for Dust in the Outflow of the HH212 Class 0 Protostellar System
Perhaps the most visually striking phenomenon during star formation is the ejection of material along the direction of the protostar's rotational axis.The ALMA-QUARKS Survey. IV. Core Mass Function and Evolutionary Trends in Core Formation Efficiency and Chemistry
The ALMA-QUARKS (Querying Underlying Mechanisms of Massive Star Formation with ALMA-Resolved Gas Kinematics and Structures) survey targets 139 massive protoclusters selected from the ATOMS survey.What fuels the growth of stars and black holes in galaxies through cosmic time? The physics and chemistry of the interstellar medium in distant galaxies
The interplay between the baryonic matter in galaxies (gas, dust, stars) has a fundamental role in our understanding of galaxy formation and evolution through cosmic time.The optical colors of hidden spiral-like features in nine Virgo early--type dwarfs
Dwarf early-type galaxies (ETGs) are abundant in nearby clusters and provide a key laboratory for studying environmentally driven galaxy transformation.Unveiling the Baryon Cycle Through Cosmic Time
Galaxy evolution is governed by the baryon cycle: gas accreted from the cosmic web and circumgalactic medium condenses into molecular gas, forms stars, and is redistributed by stellar and AGN…Self Calibrated Galaxy Groups from the DESI DR1 Bright Galaxy Survey
We present a galaxy group catalog built from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey, using the Self Calibrated Group Finder.JWST reveals a highly ionized nebula powered by an ultraluminous X-ray source with a massive black hole in the metal-poor galaxy Holmberg II
Recent James Webb Space Telescope (JWST) observations have revealed fine-structure lines of ions with ionization potentials ${\gtrsim}50$\,eV, such as [Ne\,{\sc v}] and [O\,{\sc iv}], in nebular…ACACIAS II: element abundances for 39 stars in the dwarf galaxy Sculptor
Element abundances in nearby galaxies provide insights into their chemical enrichment histories and place the Milky Way and its neighbours in a broader cosmological context.Sulphur-bearing molecule survey towards prestellar and starless cores in the Perseus molecular cloud
Sulphur is drastically depleted from the gas phase in dense starless and prestellar cores, creating the long-standing "missing sulphur problem".
