Using very deep, high spectral resolution data from the SAMI Integral Field Spectrograph, we study the stellar population properties of a sample of dwarf galaxies in the Fornax Cluster, down to a stellar mass of 10 7 M ⊙, which has never been done outside the Local Group. We use full spectral fitting to obtain stellar population parameters. Adding

The local Cosmic Ray (CR) energy spectrum exhibits a spectral softening at energies around 3 PeV. Sources which are capable of accelerating hadrons to such energies are called hadronic PeVatrons. However, hadronic PeVatrons have not yet been firmly identified within the Galaxy. Several source classes, including Galactic Supernova Remnants (SNRs)

The improved High-resolution Fast Imager (HiFI+) is a multiwavelength imaging filtergraph, which was commissioned at the GREGOR solar telescope at Observatorio del Teide, Izaña, Tenerife, Spain, in March 2022 - followed by science verification in April 2022, after which it entered routine observations. Three camera control computers with two

This a major release with a significant change of the sampler. It is now able to correctly sample likelihood functions with plateaus, (i.e likelihood functions with areas where likelihood value is exactly the same). The previous behaviour also led to inaccurate log(Z) estimates if some fraction of the prior volume had log(P)=-LARGENUMBER

The new capabilities that JWST offers in the near- and mid-infrared (IR) are used to investigate in unprecedented detail the nature of optical/near-IR-faint, mid-IR-bright sources, with HST-dark galaxies among them. We gather JWST data from the CEERS survey in the Extended Groth Strip, jointly with HST data, and analyze spatially resolved optical
