ALMA observations towards M83 reveal N2H+ tracing dense gas
Galactic observations have shown that N2H+ intensities preferentially trace star-forming dense molecular gas compared with HCN or HCO+, which are conventionally used as dense-gas tracers in…An Energetic Consistency Test for Feedback-Driven Gas Loss in Milky Way Dwarf Satellites
Dwarf spheroidal galaxies (dSphs) contain little detectable cold gas, but the relative roles of stellar feedback, reionization, and environmental effects in their gas loss remain uncertain.A machine-learning-driven dataset of 144,111 polycyclic aromatic hydrocarbon infrared spectra for interpreting aromatic infrared bands
The interpretation of interstellar aromatic infrared bands (AIBs) relies on reference spectral libraries, but the chemical space covered by existing databases remains incomplete relative to the vast…Dust Activity Evolution and Constraints on Icy Grains in the Interstellar Comet 3I/ATLAS
We present Zwicky Transient Facility observations of the interstellar comet 3I/ATLAS to characterize its dust-activity evolution before and after perihelion.The Birth and Early Feedback of Massive Star Clusters Across the Local Universe
Young massive star clusters (YMCs; ${\gtrsim}10^4\rm\,M_\odot$) represent a distinct, extreme mode of star formation and the closest present-day analogues of the environments in which globular…Disk tilts in Milky Way-like galaxies and their link to mergers
We investigated disk reorientation and its relationship to mergers in a sample of 93 Milky Way-mass galaxies drawn from the TNG50 simulations.Are High-EW LAEs good analogs for the earliest galaxies? A study on the ionizing conditions and gas properties of LAEs at $2\lesssim z\lesssim7
Lyman-$α$ emitters (LAEs) are frequently proposed as analogs of the low-mass, metal-poor galaxies thought to dominate cosmic reionization.Unveiling star formation at sub-solar metallicity with ALMA2040
A fundamental question in astrophysics is whether the processes governing star formation are universal or depend on the physical conditions of their local galactic environment.Resolving the Assembly of Disk Galaxies from the Epoch of Reionisation to Cosmic Noon
Most of the mass and angular momentum of today's disk galaxies assembled at $z>1$.Dust at cosmic dawn: unveiling the onset of dust and obscured star formation at $z\gtrsim8$
Although less than 1 percent of the baryonic mass budget of a galaxy, cosmic dust profoundly alters the multi-wavelength appearance of galaxies across cosmic time.Probing cold gas and dust in quiescent galaxies across cosmic time
The discovery of massive quiescent galaxies at high redshift by JWST has revealed that star formation can cease rapidly in the early Universe, yet the physical mechanisms responsible for quenching…Direct measures of black hole masses through cosmic time
Supermassive black holes (BHs) are thought to reside in all massive galaxies.A ${}^{13}$CO Detection in a Massive Molecular Gas Flow in Abell 1795's Central Galaxy
We present new ALMA ${}^{13}$CO(2-1) observations of the central galaxy in the cool-core cluster Abell 1795, targeting the origin of extended molecular filaments.A clump population framework for star formation across galactic scales
Whether star formation across different spatial scales and galactic environments follows universal laws remains poorly understood.Thermal Sunyaev-Zel'dovich Effect in the circumgalactic medium - III: does richness matter?
We measure the thermal Sunyaev-Zel'dovich Effect in the circumgalactic/intragroup medium (CGM/IGrM) of 7 million $\rm M_{200c} = 10^{12-14}$M$_\odot$ $z \leqslant 1$ DESI Legacy Survey…Tracking the flow of interstellar gas across scales: from galaxies to star clusters
While the baryon cycle of the interstellar medium - and its ability to form stars - plays a key role in galaxy evolution, unravelling the physical processes driving its evolution remains a critical…AGN Feeding and Feedback: Resolving the Torus
Active Galactic Nuclei (AGN) play a key role in galaxy evolution by regulating star formation within their host galaxies.Molecular atlas of nearby galaxies through sensitive high-resolution multi-band molecular line surveys
Star formation and associated feedback processes play a key role in galaxy evolution.Mixed modified-gravity--modified-inertia MOND theories
It is plausible that in a more fundamental theory of MOND both gravity and inertia will differ from their Newtonian versions.Minkowski Functionals of CII Line Intensity Maps: Probing Astrophysics and Primordial Features
Line intensity mapping aims to measure the total cumulative light of spectral lines from galaxies, without resolving individual sources.
