A triple-induced merger in T Ori C, solves the proplyd lifetime problem and the curiously young shell of M42
There has long been a tension between the stellar ages in the Orion Nebula Cluster and the rapid external photoevaporation of its protoplanetary discs.PEGASUS (Pfs Emission-line GAlaxy SUrvey with Subaru): II. Metal Poor AGNs in High Equivalent-Width Narrow-Band Emitters
We present Subaru 'Ōnohi'ula Prime Focus Spectrograph (PFS) optical--NIR spectroscopic follow-up of high-equivalent-width (EW) narrow-band (NB) emission-line galaxies selected from Hyper Suprime-Cam…Comment on "Fermi-LAT Galactic Center Excess Morphology of Dark Matter in Simulations of the Milky Way Galaxy"
Muru et al. [Phys.Morphological Statistic of Milky Way-like Galaxies
We analyze the spiral morphology of 1,738 nearby galaxies with similar Hubble type of the Milky Way ($i<60^\circ$, $z<0.048$) using multi-band optical images from the Sloan Digital Sky Survey and…Large-Scale Spiral Structure of the Milky Way Traced by Young Classical Cepheids
Using 985 classical Cepheids younger than 100 Myr, we investigate the large-scale spiral structure of the Milky Way by comparing their spatial and kinematic distributions with the R19 (four-arm) and…Trigonometric Parallaxes of Maser Sources toward the Far Side of the Milky Way
We present trigonometric parallaxes and proper motions for eight maser sources associated with high-mass star-forming regions.Improving Lens Modelling from Ground-Based Imaging with Deconvolution
Accurate and precise mass modelling of strong lensing systems is essential for extracting insights into cosmology, galaxy environments, and the nature of dark matter.A Study on the Evolution of NGC6822. I. Investigating the Star Formation History through Evolved Stellar Populations
NGC6822 is an isolated dwarf irregular galaxy in the Local Group at a distance of $\sim$ 490 kpc .Toward Resolution Convergence for Star Formation and Galactic Winds in Galaxy Simulations
The predictive power of hydrodynamic simulations of galaxies is often hampered by the resolution dependence of sub-grid models for star formation (SF) and stellar feedback.R Coronae Borealis fadings: a dusty gas cloud eclipse model
R Coronae Borealis stars (RCBs) are hydrogen-deficient supergiants that undergo deep fading events due to transient extinction by dust.Discovery of Kolmogorov-like turbulence in the inner shell of SNR HB 9
We investigated the scaling relation of the magnetohydrodynamic turbulence in the inner and outer shells of the supernova remnant HB 9 using multi-tracers.KiDS-DR5: Exploring dust transport in dark matter halos of galaxies
We analyse a well-defined sample of galaxies from the final data release of the Kilo-Degree Survey (KiDS-DR5), selected using magnitude, photometric redshift, and stellar mass cuts, to measure their…Before fragmentation: from uniform clouds to stellar clusters
Our study of the early stages of fragmentation in massive clumps has revealed a striking anomaly: $\sim15\%$ of the CoCoA sample exhibit no fragmentation at all.DREAMS: Taking the Temperature of a Massive Galaxy at z ~ 11
We present a detailed photometric and spectroscopic analysis of Janus-11, a $z=10.7933 \pm 0.0006 $ galaxy magnified by a factor 1.6 by the galaxy cluster MACS J0416.Exploring the observed properties of JWST Little Red Dots with cosmological simulations and dust radiative transfer
JWST has uncovered compact high-redshift (z>=4) sources, dubbed Little Red Dots (LRDs), characterised by a distinct V-shaped continuum.Far-Ultraviolet diffuse emission as a tracer of Galactic extinction at the North Galactic Pole
Interstellar extinction at high Galactic latitude is often traced by thermal dust emission, but the conversion from infrared surface brightness to reddening is sensitive to grain properties and…MATISSE in the era of GRAVITY+
MATISSE, the mid-infrared spectro-interferometric imager of the Very Large Telescope Interferometer (VLTI), has been feeding on the light corrected by the GRAVITY+ Adaptive Optics (GPAO) systems…Probing Spatial Variations in IGM Transmission: Higher Ly$α$ Visibility in an H$α$-Selected Galaxy Overdensity at $z\simeq6.2$
The visibility of Ly$α$ emission during the epoch of reionization depends on both galaxy properties and the transmission of Ly$α$ photons through the intergalactic medium (IGM).The 2MIG isolated AGNs -- 4. Linking hot-dust reverberation to spectroscopically predicted BLR scales in IC~5287 and Mrk~845
We investigate the relation between directly measured hot-dust reverberation scales and spectroscopically predicted broad-line region (BLR) scales in the isolated Seyfert galaxies IC~5287 and…ViCTORIA project: A pilot study of the M49 region in the Virgo cluster in polarisation
Large-scale magnetic fields permeate the Intracluster Medium (ICM) of galaxy clusters.
