Herschel observations of extraordinary sources: full Herschel/HIFI molecular line survey of Sagittarius B2(M)
Comito, C.; Schilke, P.; Lis, D. C. +5 more
Context. We present a full analysis of a broadband spectral line survey of Sagittarius B2 (Main), one of the most chemically rich regions in the Galaxy located within the giant molecular cloud complex Sgr B2 in the central molecular zone.
Aims: Our goal is to derive the molecular abundances and temperatures of the high-mass star-forming regio…
Investigating the delay between dust radiation and star-formation in local and distant quenching galaxies
Elbaz, D.; Ciesla, L.; Buat, V. +3 more
We investigate the timescale over which the infrared (IR) luminosity decreases after a complete and rapid quenching of star formation using observations of local and high-redshift galaxies. From spectral energy distribution modelling, we derive the time since quenching of a subsample of 14 galaxies from the Herschel Reference Survey that suffer fr…
S2D2: Small-scale Significant substructure DBSCAN Detection. I. NESTs detection in 2D star-forming regions
Hacar, Álvaro; Buckner, Anne S. M.; González, Marta +13 more
Context. The spatial and dynamical structure of star-forming regions can offer insights into stellar formation patterns. The amount of data from current and upcoming surveys calls for robust and objective procedures for detecting structures in order to statistically analyse the various regions and compare them.
Aims: We aim to provide the com…
Switchback-like structures observed by Solar Orbiter
Fedorov, A.; Lavraud, B.; Andre, N. +19 more
Context. Rapid polarity reversals of the radial heliospheric magnetic field were discovered by Ulysses and they are now frequently observed as a common near-Sun phenomenon by NASA's Parker Solar Probe (PSP). Other solar wind missions, including ESA-NASA Solar Orbiter (SolO), also observe similar phenomena. The nature of these fluctuations is uncle…
Multiwavelength view of SPT-CL J2106-5844. The radio galaxies and the thermal and relativistic plasmas in a massive galaxy cluster merger at z ≃ 1.13
Koribalski, Bärbel S.; Churazov, Eugene; Hopkins, Andrew M. +12 more
Context. SPT-CL J2106-5844 is among the most massive galaxy clusters at z > 1 yet discovered. While initially used in cosmological tests to assess the compatibility with Λ Cold Dark Matter cosmology of such a massive virialized object at this redshift, more recent studies indicate SPT-CL J2106-5844 is undergoing a major merger and is not an iso…
Magnetic properties on the boundary of an evolving pore
Jurčák, J.; Bello González, N.; García-Rivas, M.
Context. Analyses of the magnetic properties on umbrae boundaries have led to the Jurčák criterion, which states that umbra-penumbra boundaries in stable sunspots are equally defined by a constant value of the vertical magnetic field, Bvercrit, and by a 50% continuum intensity of the quiet Sun, IQS. Umbrae with ver…
The GRAVITY young stellar object survey. IV. The CO overtone emission in 51 Oph at sub-au scales
Genzel, R.; Sturm, E.; Labadie, L. +69 more
Context. 51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 µm, most likely originating in the innermost regions of a circumstellar disc.
Aims: We aim to obtain the physical and geometrical properties of the system by spatially resolving the circumstellar environment of the inner gaseous d…
Multiwavelength dissection of a massive heavily dust-obscured galaxy and its blue companion at z∼2
Daddi, E.; Béthermin, M.; Ciesla, L. +4 more
Aims: We study a system of two galaxies, Astarte and Adonis, at z ∼ 2. At this time, the Universe was undergoing the peak of its star formation activity. Astarte is a dusty star-forming galaxy at the massive end of the main sequence (MS), and Adonis is a less massive companion galaxy that is bright in the ultraviolet and has an optical spectr…
A super-Earth on a close-in orbit around the M1V star GJ 740. A HADES and CARMENES collaboration
Rebolo, R.; Amado, P. J.; Caballero, J. A. +23 more
Context. M-dwarfs have proven to be ideal targets for planetary radial velocity (RV) searches due to their higher planet-star mass contrast, which favors the detection of low-mass planets. The abundance of super-Earth and Earth-like planets detected around this type of star motivates further such research on hosts without reported planetary compan…
High-resolution Hα imaging of the northern Galactic plane and the IGAPS image database
Eislöffel, J.; Groot, P. J.; Stecklum, B. +19 more
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys IPHAS and UVEX based on data from the Isaac Newton Telescope (INT) obtained between 2003 and 2018. It captures the entire northern Galactic plane within the Galactic coordinate range |b|< 5° and 30° < ℓ < 215°. From the beginning, the incorporation of n…
