Neutron-capture Elements in Planetary Nebulae: First Detections of Near-infrared [Te III] and [Br V] Emission LinesWe have identified two new near-infrared (NIR) emission lines in the spectra of planetary nebulae arising from heavy elements produced by neutron-capture reactions: [Te III] 2.1019 μm and [Br V] 1.6429 μm. [Te III] was detected in both NGC 7027 and IC 418, while [Br V] was seen in NGC 7027. The observations were obtained with the medium-resolutionMadonna, S. et al.

Multimessenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922APrevious detections of individual astrophysical sources of neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neutrinos remain unidentified. On 22 September 2017, we detected a high-energy neutrino, IceCube-170922A, with an energy of ~290 tera-electron volts. Its arrival directionIceCube Collaboration et al.

MHDSTS: a new explicit numerical scheme for simulations of partially ionised solar plasmaThe interaction of plasma with magnetic field in the partially ionised solar atmosphere is frequently modelled via a single-fluid approximation, which is valid for the case of a strongly coupled collisional media, such as solar photosphere and low chromosphere. Under the single-fluid formalism the main non-ideal effects are described by a series ofGonzález-Morales, P. A. et al.

Merging light beams from the 4 VLT telescopesESPRESSO is a fiber feed ultrastable High Resolution Spectrograph designed to work in the Combined-Coudé focus of Very Large Telescopes (VLT). A high resolution (R 100000) and an ultra-high resolution (R 220000) mode will be available to collect the light coming of one VLT telescope. In addition, ESPRESSO has an observing mode which allows toGracia Temich, Felix et al.

MEGARA, the R=6000-20000 IFU and MOS of GTCMEGARA is the new generation IFU and MOS optical spectrograph built for the 10.4m Gran Telescopio CANARIAS (GTC). The project was developed by a consortium led by UCM (Spain) that also includes INAOE (Mexico), IAA-CSIC (Spain) and UPM (Spain). The instrument arrived to GTC on March 28th 2017 and was successfully integrated and commissioned at theCarrasco, E. et al.
