The softness diagram for MaNGA star-forming regions: diffuse ionized gas contamination or local HOLMES predominance?
Enrique Pérez-Montero, Igor Zinchenko, José M. Vílchez +3
We explore the so-called softness diagram -- whose main function is to provide the hardness of the ionizing radiation in star-forming regions -- in order to check whether hot and o…
The gas and stellar content of a metal-poor galaxy at as revealed by JWST and ALMA
K. E. Heintz, C. Giménez-Arteaga, S. Fujimoto +27
We present a joint analysis of the galaxy S04590 at based on NIRSpec, NIRCam, and NIRISS observations obtained through as part of Early Release Observations programme of…
Understanding the role of morphology and environment on the dynamical evolution of isolated galaxy triplets
P. Vásquez-Bustos, M. Argudo-Fernández, D. Grajales-Medina +2
The environment where galaxies reside affects their evolutionary histories. Galaxy triplets (systems composed of three physically bound galaxies) constitute one of simplest group o…
MEGADES: MEGARA Galaxy Discs Evolution Survey. Data Release I: central fields
M. Chamorro-Cazorla, A. Gil de Paz, A. Castillo-Morales +12
The main interest of the Science Team for the exploitation of the MEGARA instrument at the 10.4m Gran Telescopio Canarias (GTC hereafter) is devoted to the study of nearby galaxies…
Fast Multipole Method for Gravitational Lensing. Application to High Magnification Quasar Microlensing
J. Jiménez Vicente, E. Mediavilla
We introduce the use of the Fast Multipole Method (FMM) to speed up gravitational lensing ray tracing calculations. The method allows very fast calculation of ray deflections when…
CO(=1-0) mapping survey of 64 galaxies in the Fornax cluster with the ALMA Morita array
Kana Morokuma-Matsui, Kenji Bekki, Jing Wang +18
We conduct a CO(=1-0) (hereafter CO) mapping survey of 64 galaxies in the Fornax cluster using the ALMA Morita array in cycle 5. CO emission is detected from 23 ou…
SIT 45: An interacting, compact, and star-forming isolated galaxy triplet
D. Grajales-Medina, M. Argudo-Fernández, P. Vásquez-Bustos +7
The merging system SIT 45 (UGC 12589) is an unusual isolated galaxy triplet, consisting of three merging late-type galaxies, out of 315 systems in the SIT (SDSS-based catalogue of…
Metal-Enriched Neutral Gas Reservoir around a Strongly-lensed, Low-mass Galaxy at Identified by JWST/NIRISS and VLT/MUSE
Xiaojing Lin, Zheng Cai, Siwei Zou +19
Direct observations of low-mass, low-metallicity galaxies at provide an indispensable opportunity for detailed inspection of the ionization radiation, gas flow, and met…
SOFIA/HAWC+ observations of the Crab Nebula: dust properties from polarised emission
Jérémy Chastenet, Ilse De Looze, Brandon S. Hensley +14
Supernova remnants (SNRs) are well-recognised dust producers, but their net dust production rate remains elusive due to uncertainties in grain properties that propagate into observ…
Dust grain size evolution in local galaxies: a comparison between observations and simulations
M. Relano, I. De Looze, A. Saintonge +13
The evolution of the dust grain size distribution has been studied in recent years with great detail in cosmological hydrodynamical simulations taking into account all the channels…
ALMA Lensing Cluster Survey: and Photometry of 33 Lensed Fields Built with CHArGE
Vasily Kokorev, Gabriel Brammer, Seiji Fujimoto +30
We present a set of multi-wavelength mosaics and photometric catalogs in the ALMA lensing cluster survey (ALCS) fields. The catalogs were built by reprocessing of archival data fro…
Dark matter halos and scaling relations of extremely massive spiral galaxies from extended HI rotation curves
Enrico M. Di Teodoro, Lorenzo Posti, S. Michael Fall +6
We present new and archival atomic hydrogen (\hi) observations of \galnum\ of the most massive spiral galaxies in the local Universe (). From 3…
ALMA Lensing Cluster Survey: ALMA-Herschel Joint Study of Lensed Dusty Star-Forming Galaxies across
Fengwu Sun, Eiichi Egami, Seiji Fujimoto +25
We present an ALMA-Herschel joint analysis of sources detected by the ALMA Lensing Cluster Survey (ALCS) at 1.15 mm. Herschel/PACS and SPIRE data at 100-500 m are deblended for…
Unveiling the past evolution of the progenitor of the Helmi streams
T. Ruiz-Lara, A. Helmi, C. Gallart +2
We aim to determine unique features that characterise the past evolution of the progenitor of the Helmi streams through the analysis of star formation histories (SFHs). From the 5D…
Distance to the Brick cloud using stellar kinematics
Á. Martínez-Arranz, R. Schödel, F. Nogueras-Lara +1
Context. The central molecular zone at the Galactic center is currently being studied intensively to understand how star formation proceeds under the extreme conditions of a galact…
The CO emission in the Taffy Galaxies (UGC 12914/5) at 60pc resolution-I: The battle for star formation in the turbulent Taffy Bridge
P. N. Appleton, B. Emonts, U. Lisenfeld +8
We present ALMA observations at a spatial resolution of 0.2 arcsec (60 pc) of CO emission from the Taffy galaxies (UGC 12914/5). The observations are compared with narrow-band Pa$α…
