Hyperspectral imaging of meteorites using the HyperScout-H instrument
Introduction The cosine* HyperScout-H (HS-H) instrument will fly aboard the ESA/Hera spacecraft. This mission [1], focused on planetary defense, aims to...
We identify candidate hypervelocity stars from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) G and K dwarf samples. Previous searches...
H_α luminosities of a sample of galaxies in nearby compact groups are presented. Our purpose is to study the influence of the group environment on the star...
Hα emission line sources from IPHAS (Witham+, 2008)
We present IPHAS positions and photometry for 4853 sources selected as having a Hα excess from the photometry. The catalogue covers the magnitude range 13
Hα kinematics of nearby galaxies using Fabry-Perot and IFU data
I present here analysis of the shapes of the rotation curves of a large sample of nearby spiral galaxies with high angular and spectral resolution Hα (Fabry...
Hα luminosity function of H II regions: preliminary calibration of a powerful standard candle
We propose the use of the H II region luminosity function (LF) as a refined powerful standard candle for extragalactic distances. We have found evidence of a...
Presenting the first detection of a peanut structure in the inner bar of a double-barred system! Peanuts are formed after the buckling of stellar bars. Having...
