Using JWST/MIRI observations, we report the detection of CO $_{2}$ ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…

WISDOM Project - XXVII. Giant molecular clouds of the lenticular galaxy NGC 1387: similarities with spiral galaxy clouds

Fu-Heng Liang, Martin Bureau, Lijie Liu +10

Molecular gas is crucial to understanding star formation and galaxy evolution, but the giant molecular clouds (GMCs) of early-type galaxies (ETGs) have rarely been studied. Here, w…

MAJORS II: HCO+& HCN Abundances in W40

René Plume, David J. Eden, Malcolm J. Currie +34

We present observations of HCN and HCO $^{+}$ J = $3 - 2$ in the central $42 4^{''} \times 42 4^{''}$ region of the W40 massive star forming region. The observations were taken as part of a p…

Stirring Things Up: Bar-induced substructures in the stellar halo of a cosmological Milky Way analogue

Thomas Tomlinson, Francesca Fragkoudi, Andreia Carrillo +8

The stellar halo of the Milky Way contains the remnants of past accretion events, which could be detectable as substructures in the classical integrals of motion space, such as ene…

The influence of magnetic fields in Cloud-Cloud Collisions

Theotokis Georgatos, Anthony P. Whitworth

Cloud-cloud collisions are expected to trigger star formation by compressing gas into dense, gravitationally unstable regions. However, the role of magnetic fields in this process…

The contribution of stars, dust, neutral gas and supermassive black holes in galaxies to the cosmic baryon inventory

Jordan C. J. D'Silva, Simon P. Driver, Aaron S. G. Robotham +5

We compute the cosmic stellar, dust and neutral gas mass history at $0 < z ≲ 3$ using ProSpect spectral energy distribution modelling of $\approx 800000$ galaxies in the Gal…

A large, long-lived, slowly-expanding superbubble across the Perseus Arm

Bingqiu Chen, Guangxing Li, Haibo Yuan +5

Stellar feedback is a crucial mechanism in galactic evolution, as demonstrated by the widespread bubbles observed with JWST. In this study, we combine data from Gaia and LAMOST to…

NIKA2 Cosmological Legacy Survey. First measurement of the confusion noise at the IRAM 30 m telescope

N. Ponthieu, F. -X. Désert, A. Beelen +54

The NIKA2 Cosmological Legacy Survey (N2CLS) is a large programme using the NIKA2 dual-band camera on the IRAM 30\,m telescope. Its goal is to improve our understanding of the phys…

Kennicutt-Schmidt relation of galaxies over 13 billion years in the COLIBRE hydrodynamical simulations

Claudia del P. Lagos, Joop Schaye, Matthieu Schaller +16

We investigate the correlation between star formation rate (SFR) surface density and gas surface density (known as the Kennicutt-Schmidt, KS, relation) at kiloparsec (kpc) scales a…

Euclid: The first statistical census of dusty and massive objects in the ERO/Perseus field

G. Girardi, A. Grazian, G. Rodighiero +175

Our comprehension of the history of star formation at $z > 3$ relies on rest-frame UV observations, yet this selection misses the most dusty and massive sources, yielding an incomple…
