We present results obtained from a spectroscopic analysis of high-resolution spectra taken with the ESPADONS spectrograph at the Canada-France-Hawaii Telescope and the SOPHIE spectrograph installed at the telescope in Haute-Provence Observatory. The data were collected for A- and F-type stars observed in the Kepler field. The presented sample of

We present a software simulator for the modeling of astronomical instrumentation, which includes platform effects and software processing. It is an end-to-end simulator, from the entrance of the telescope to the data acquisition at the detector, along with software blocks dealing, e.g., with demodulation, inversion, and compression. Developed

The Shocked POststarburst Galaxy Survey (SPOGS) aims to identify galaxies in the transitional phase between actively star-forming and quiescence with nebular lines that are excited from shocks rather than star formation processes. We explored the ultraviolet (UV) properties of objects with near-ultraviolet (NUV) and far-ultraviolet (FUV) photometry

Rotating magnetic structures are common in astrophysics, from vortex tubes and tornadoes in the Sun all the way to jets in different astrophysical systems. The physics of these objects often combine inertial, magnetic, gas pressure, and gravitational terms. Also, they often show approximate symmetries that help simplify the otherwise rather

A search for a narrow-width resonance decaying into two Higgs bosons, each decaying into a bottom quark-antiquark pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 35.9 fb-1 at √{s}=13 TeV recorded by the CMS detector at the LHC. No evidence for such a signal is observed

Results are reported from a search for physics beyond the standard model in proton-proton collisions at a center-of-mass energy of √{ s } = 13TeV. The search uses a signature of a single lepton, large jet and bottom quark jet multiplicities, and high sum of large-radius jet masses, without any requirement on the missing transverse momentum in an
