Extreme solar events
DOI: 10.1007/s41116-022-00033-8 Bibcode: 2022LRSP...19....2C

Shibata, Kazunari; Schrijver, Carolus J.; Usoskin, Ilya G. +1 more

We trace the evolution of research on extreme solar and solar-terrestrial events from the 1859 Carrington event to the rapid development of the last twenty years. Our focus is on the largest observed/inferred/theoretical cases of sunspot groups, flares on the Sun and Sun-like stars, coronal mass ejections, solar proton events, and geomagnetic stor…

SDSS-IV MaNGA: pyPipe3D Analysis Release for 10,000 Galaxies
DOI: 10.3847/1538-4365/ac7b8f Bibcode: 2022ApJS..262...36S

Bruzual, Gustavo; Sánchez, S. F.; Barrera-Ballesteros, J. K. +12 more

We present here the analysis performed using the pyPipe3D pipeline for the final MaNGA data set included in the Sloan Digital Sky Survey data release 17. This data set comprises more than 10,000 individual data cubes, being the integral field spectroscopic (IFS) galaxy survey with the largest number of galaxies. pyPipe3D processes the IFS data cub…

The R136 star cluster dissected with Hubble Space Telescope/STIS. III. The most massive stars and their clumped winds
DOI: 10.1051/0004-6361/202142742 Bibcode: 2022A&A...663A..36B

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…

A tale of two DIGs: The relative role of H II regions and low-mass hot evolved stars in powering the diffuse ionised gas (DIG) in PHANGS-MUSE galaxies
DOI: 10.1051/0004-6361/202141859 Bibcode: 2022A&A...659A..26B

Boquien, M.; Chevance, M.; Kruijssen, J. M. Diederik +17 more

We use integral field spectroscopy from the PHANGS-MUSE survey, which resolves the ionised interstellar medium structure at ∼50 pc resolution in 19 nearby spiral galaxies, to study the origin of the diffuse ionised gas (DIG). We examine the physical conditions of the diffuse gas by first removing morphologically defined H II regions and then binni…

The GALAH Survey: chemical tagging and chrono-chemodynamics of accreted halo stars with GALAH+ DR3 and Gaia eDR3
DOI: 10.1093/mnras/stab3504 Bibcode: 2022MNRAS.510.2407B

Lewis, Geraint F.; Ting, Yuan-Sen; Feuillet, Diane K. +27 more

Since the advent of Gaia astrometry, it is possible to identify massive accreted systems within the Galaxy through their unique dynamical signatures. One such system, Gaia-Sausage-Enceladus (GSE), appears to be an early 'building block' given its virial mass $\gt 10^{10}\, \mathrm{M_\odot }$ at infall (z ~ 1-3). In order to separate the progenitor…

Structural parameters of 389 local open clusters
DOI: 10.1051/0004-6361/202142186 Bibcode: 2022A&A...659A..59T

Miret-Roig, N.; Castro-Ginard, A.; Casamiquela, L. +4 more

Context. The distribution of member stars in the surroundings of an open cluster (OC) can shed light on the process of its formation, evolution, and dissolution. The analysis of structural parameters of OCs as a function of their age and position in the Galaxy constrains theoretical models of cluster evolution. The Gaia catalog is very appropriate…

S 5: The Orbital and Chemical Properties of One Dozen Stellar Streams
DOI: 10.3847/1538-4357/ac46d3 Bibcode: 2022ApJ...928...30L

Lewis, Geraint F.; Erkal, Denis; Bland-Hawthorn, Joss +18 more

We report the kinematic, orbital, and chemical properties of 12 stellar streams with no evident progenitors using line-of-sight velocities and metallicities from the Southern Stellar Stream Spectroscopic Survey (S 5), proper motions from Gaia EDR3, and distances derived from distance tracers or the literature. This data set provides the…

Gaia Early Data Release 3. The celestial reference frame (Gaia-CRF3)
DOI: 10.1051/0004-6361/202243483 Bibcode: 2022A&A...667A.148G

Prusti, T.; Mazeh, T.; Zucker, S. +448 more

Context. Gaia-CRF3 is the celestial reference frame for positions and proper motions in the third release of data from the Gaia mission, Gaia DR3 (and for the early third release, Gaia EDR3, which contains identical astrometric results). The reference frame is defined by the positions and proper motions at epoch 2016.0 for a specific set of extrag…

Ouchi, Masami; Kewley, Lisa J.; Ravindranath, Swara +46 more

Far-ultraviolet (FUV; ~1200-2000 Å) spectra are fundamental to our understanding of star-forming galaxies, providing a unique window on massive stellar populations, chemical evolution, feedback processes, and reionization. The launch of the James Webb Space Telescope will soon usher in a new era, pushing the UV spectroscopic frontier to higher red…

A stringent upper limit on dark matter self-interaction cross-section from cluster strong lensing
DOI: 10.1093/mnras/stab3241 Bibcode: 2022MNRAS.510...54A

Andrade, Kevin E.; Fuson, Jackson; Gad-Nasr, Sophia +4 more

We analyse strongly lensed images in eight galaxy clusters to measure their dark matter density profiles in the radial region between 10 kpc and 150 kpc, and use this to constrain the self-interaction cross-section of dark matter (DM) particles. We infer the mass profiles of the central DM haloes, bright central galaxies, key member galaxies, and …
