Packed Ultra-wideband Mapping Array (PUMA): A Radio Telescope for Cosmology and TransientsPUMA is a proposed ultra-wideband low-resolution interferometric transit radio telescope operating at 200-1100 MHz composed of thousands of 6m dishes. It is optimized for intensity mapping of the redshifted 21cm line over z=0.3-6 to study dark energy and inflation. The same design also allows an unprecedented study of fast radio bursts and pulsars.Slosar, Anze et al.

On the Use of Field RR Lyrae as Galactic Probes. I. The Oosterhoff Dichotomy Based on Fundamental VariablesWe collected a large data set of field RR Lyrae stars (RRLs) by using catalogs already available in the literature and Gaia DR2. We estimated the iron abundances for a subsample of 2382 fundamental RRLs (∆S method: Ca II K, Hβ, Hγ, and Hδ lines) for which there are publicly available medium-resolution SDSS-SEGUE spectra. We also included similarFabrizio, M. et al.

NGC 7457: evidence for merger-driven cylindrical rotation in disc galaxiesWe construct Schwarzschild orbit-based models of NGC 7457, known as a peculiar low-mass lenticular galaxy. Our best-fitting model successfully retrieves most of the unusual kinematics behaviours of this galaxy, in which, the orbital distribution of stars is dominated by warm and hot orbits. The reconstructed surface brightness of the hot componentMolaeinezhad, A. et al.

Multivariable statistical analysis of spectrophotometry and spectra of (162173) Ryugu as observed by JAXA Hayabusa2 missionContext. Starting from late June 2018, the JAXA asteroid sample return mission Hayabusa2 acquired a large quantity of resolved images and spectra of the surface of the asteroid (162173) Ryugu. Aims: By studying the visible and near-infrared spectral behavior across the surface of Ryugu using a statistical analysis, we aim to distinguish spectralBarucci, M. A. et al.

Monte Carlo studies for the optimisation of the Cherenkov Telescope Array layoutThe Cherenkov Telescope Array (CTA) is the major next-generation observatory for ground-based very-high-energy gamma-ray astronomy. It will improve the sensitivity of current ground-based instruments by a factor of five to twenty, depending on the energy, greatly improving both their angular and energy resolutions over four decades in energy (fromAngüner, E. O. et al.
