The MAGPI Survey -- science goals, design, observing strategy, early results and theoretical framework
(2021-07-26)
We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on ESO/VLT. MAGPI is designed to study the physical drivers of galaxy transformation at a lookback ...
Variable stars in the VVV globular clusters. II. NGC6441, NGC6569, NGC6626 (M28), NGC6656 (M22), 2MASS-GC02, and Terzan10
(2021-07-12)
Context. The Galactic globular clusters (GGCs) located in the inner regions of the Milky Way suffer from high extinction that makes their observation challenging. High densities of field stars in their surroundings complicate ...
R-Process elements from magnetorotational hypernovae
(2021-07-08)
Neutron-star mergers were recently confirmed as sites of rapid-neutron-capture (r-process) nucleosynthesis 1–3. However, in Galactic chemical evolution models, neutron-star mergers alone cannot reproduce the observed element ...
The eROSITA Final Equatorial-Depth Survey (eFEDS). LOFAR view of brightest cluster galaxies and AGN feedback
(2021-07-06)
Context. During the performance verification phase of the Spectrum-Roentgen-Gamma (SRG) eROSITA telescope, the eROSITA Final Equatorial-Depth Survey (eFEDS) was carried out. It covers a 140 deg2 field located at 126◦ < ...
Transient obscuration event captured in NGC 3227. I. Continuum model for the broadband spectral energy distribution
(2021-06-28)
From Swift monitoring of a sample of active galactic nuclei (AGN) we found a transient X-ray obscuration event in Seyfert-1 galaxy NGC 3227, and thus triggered our joint XMM-Newton, NuSTAR, and Hubble Space Telescope (HST) ...
Constraining AGN duty cycle in the cool-core cluster MS 0735.6+7421 with LOFAR data
(2021-06-25)
MS 0735.6+7421 is a galaxy cluster which hosts a central radio galaxy with a very steep spectrum, produced by one of the most powerful known jetted active galactic nuclei (AGN). The radio plasma, ejected at nearly light ...
The ultraviolet luminosity function of star-forming galaxies between redshifts of 0.6 and 1.2
(2021-06-14)
We use ultraviolet (UV) imaging taken with the XMM–Newton Optical Monitor telescope (XMM-OM), covering 280 arcmin2 in the UVW1 band (λeff = 2910 Å) to measure rest-frame UV 1500-Å luminosity functions of galaxies with ...
Discovery of a new nearby globular cluster with extreme kinematics located in the extension of a halo stream
(2021-06-01)
Context. We report the discovery of VVV-CL160, a new nearby globular cluster (GC) with extreme kinematics, located in the Galactic plane at l = 10.1477 deg, b = 0.2999 deg. Aims. We aim to characterize the physical properties ...
Raining in MKW 3 s: a Chandra-MUSE analysis of X-ray cold filaments around 3CR 318.1
(2021-05-10)
We present the analysis of X-ray and optical observations of gas filaments observed in the radio source 3CR 318.1, associated with NGC 5920, the Brightest Cluster Galaxy (BCG) of MKW 3s, a nearby cool core galaxy cluster. ...
The JCMT BISTRO Survey: Revealing the diverse magnetic field morphologies in Taurus dense cores with sensitive sub-millimeter polarimetry
(2021-05-10)
We have obtained sensitive dust continuum polarization observations at 850 $\mu$m in the B213 region of Taurus using POL-2 on SCUBA-2 at the James Clerk Maxwell Telescope (JCMT), as part of the BISTRO (B-fields in STar-forming ...
