The PHANGS-MUSE survey. Probing the chemo-dynamical evolution of disc galaxies
Sandstrom, Karin M.; Henshaw, Jonathan D.; Kruijssen, J. M. Diederik +45 more
We present the PHANGS-MUSE survey, a programme that uses the MUSE integral field spectrograph at the ESO VLT to map 19 massive (9.4 < log(M⋆/M⊙)< 11.0) nearby (D ≲ 20 Mpc) star-forming disc galaxies. The survey consists of 168 MUSE pointings (1' by 1' each) and a total of nearly 15 × 106 spectra, covering ∼1.…
Gaia early DR3 systemic motions of Local Group dwarf galaxies and orbital properties with a massive Large Magellanic Cloud
Fritz, T. K.; Battaglia, G.; Taibi, S. +1 more
Aims: We perform a comprehensive determination of the systemic proper motions of 74 dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia early data release 3. The outputs of the analysis for each galaxy, including probabilities of membership, will be made publicly available. The analysis is augmented by a determination …
The R136 star cluster dissected with Hubble Space Telescope/STIS. III. The most massive stars and their clumped winds
Sana, Hugues; Vink, Jorick S.; Kaper, Lex +17 more
Context. The star cluster R136 inside the Large Magellanic Cloud hosts a rich population of massive stars, including the most massive stars known. The strong stellar winds of these very luminous stars impact their evolution and the surrounding environment. We currently lack detailed knowledge of the wind structure that is needed to quantify this i…
GOODS-ALMA 2.0: Source catalog, number counts, and prevailing compact sizes in 1.1 mm galaxies
Magnelli, B.; Daddi, E.; Elbaz, D. +35 more
Submillimeter/millimeter observations of dusty star-forming galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA) have shown that dust continuum emission generally occurs in compact regions smaller than the stellar distribution. However, it remains to be understood how systematic these findings are. Studies often lack homogeneity i…
Supermassive black holes at high redshift are expected to be obscured by their massive host galaxies' interstellar medium
Pozzi, F.; Vignali, C.; Gilli, R. +12 more
We combine results from deep ALMA observations of massive (M* > 1010 M⊙) galaxies at different redshifts to show that the column density of their interstellar medium (ISM) rapidly increases toward early cosmic epochs. Our analysis includes objects from the ASPECS and ALPINE large programs, as well as individual …
High star cluster formation efficiency in the strongly lensed Sunburst Lyman-continuum galaxy at z = 2.37
Zanella, A.; Brammer, G.; Castellano, M. +16 more
We investigate the strongly lensed (µ ≃ ×10 − 100) Lyman continuum (LyC) galaxy, dubbed Sunburst, at z = 2.37, taking advantage of a new accurate model of the lens. A characterization of the intrinsic (delensed) properties of the system yields a size of ≃3 sq. kpc, a luminosity of MUV = −20.3, and a stellar mass of M ≃ 109
The Low-Redshift Lyman Continuum Survey. Unveiling the ISM properties of low-z Lyman-continuum emitters
Giavalisco, Mauro; Grazian, Andrea; Pentericci, Laura +24 more
Aims: Combining 66 ultraviolet (UV) spectra and ancillary data from the recent Low-Redshift Lyman Continuum Survey (LzLCS) and 23 LyC observations by earlier studies, we form a statistical sample of star-forming galaxies at z ∼ 0.2 − 0.4 with which we study the role of cold interstellar medium (ISM) gas in the leakage of ionizing radiation. W…
COSMOS2020: Cosmic evolution of the stellar-to-halo mass relation for central and satellite galaxies up to z ∼ 5
Sanders, D. B.; Ilbert, O.; Moneti, A. +13 more
We used the COSMOS2020 catalog to measure the stellar-to-halo mass relation (SHMR) divided by central and satellite galaxies from z = 0.2 to z = 5.5. Starting from accurate photometric redshifts, we measured the near-infrared selected two-point angular correlation and stellar mass functions in ten redshift bins. We used a phenomenological model th…
The diverse cold molecular gas contents, morphologies, and kinematics of type-2 quasars as seen by ALMA
Tadhunter, C. N.; Feruglio, C.; García-Burillo, S. +8 more
We present CO(2−1) and adjacent continuum observations of seven nearby radio-quiet type-2 quasars (QSO2s) obtained with ALMA at ∼0.2″ resolution (370 pc at z ∼ 0.1). These QSO2s are luminous (L[OIII] > 108.5 L⊙ ∼ MB < −23), and their host galaxies massive (M* ∼ 1011 M⊙
Search of strong lens systems in the Dark Energy Survey using convolutional neural networks
Clément, B.; Courbin, F.; Joseph, R. +8 more
We present our search for strong lens, galaxy-scale systems in the first data release of the Dark Energy Survey (DES), based on a color-selected parent sample of 18 745 029 luminous red galaxies (LRGs). We used a convolutional neural network (CNN) to grade this LRG sample with values between 0 (non-lens) and 1 (lens). Our training set of mock lens…
