ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT). VI. Accretion shocks in the disk of DG Tau and HL Tau
Podio, L.; Bacciotti, F.; Fedele, D. +9 more
Planet-forming disks are not isolated systems. Their interaction with the surrounding medium affects their mass budget and chemical content. In the context of the ALMA-DOT program, we obtained high-resolution maps of assorted lines from six disks that are still partly embedded in their natal envelope. In this work, we examine the SO and SO2
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
Three-dimensional extinction maps: Inverting inter-calibrated extinction catalogues
Lallement, R.; Cox, N. L. J.; Vergely, J. L.
Context. Three-dimensional (3D) maps of the extinction density in the Milky Way can be built through the inversion of large catalogues of distance-extinction pairs for individual target stars. Considerable progress is currently achieved in this field through the Gaia mission. Available catalogues are based on various types of photometric or spectr…
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…
Probing inner and outer disk misalignments in transition disks. Constraints from VLTI/GRAVITY and ALMA observations
Ménard, F.; Henning, T.; Ginski, C. +16 more
Context. Transition disks are protoplanetary disks with dust-depleted cavities, possibly indicating substantial clearing of their dust content by a massive companion. For several known transition disks, dark regions interpreted as shadows have been observed in scattered light imaging and are hypothesized to originate from misalignments between dis…
The Planck clusters in the LOFAR sky. I. LoTSS-DR2: New detections and sample overview
Simionescu, A.; Zhang, X.; Di Gennaro, G. +23 more
Context. Relativistic electrons and magnetic fields permeate the intra-cluster medium (ICM) and manifest themselves as diffuse sources of synchrotron emission observable at radio wavelengths, namely radio halos and radio relics. Although there is broad consensus that the formation of these sources is connected to turbulence and shocks in the ICM, …
Stellar labels for hot stars from low-resolution spectra. I. The HotPayne method and results for 330 000 stars from LAMOST DR6
Xiang, Maosheng; Conroy, Charlie; Ting, Yuan-Sen +9 more
We set out to determine stellar labels from low-resolution survey spectra of hot stars, specifically OBA stars with Teff ≳ 7500 K. This fills a gap in the scientific analysis of large spectroscopic stellar surveys such as LAMOST, which offers spectra for millions of stars at R ~ 1800 and covers 3800 Å ≤ λ ≤ 9000 Å. We first explore the …
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⊙
