X-ray optics and beam characterisation using random modulation: Experiments
Sebastien Berujon, Ruxandra Cojocaru, Pierre Piault +4
In a previous paper, we reviewed theoretically some of the available processing schemes for X-ray wavefront sensing based on random modulation. We here show experimental applicatio…
X-ray optics and beam characterization using random modulation: Theory
Sebastien Berujon, Ruxandra Cojocaru, Pierre Piault +4
X-ray near-field speckle-based phase-sensing approaches provide efficient means to characterise optical elements. Here, we present a theoretical review of several of these speckle…
The population of white dwarf-main sequence binaries in the SDSS DR 12
R. Cojocaru, A. Rebassa-Mansergas, S. Torres +1
We present a Monte Carlo population synthesis study of white dwarf-main sequence (WD+MS) binaries in the Galactic disk aimed at reproducing the ensemble properties of the entire po…
The age-metallicity relation in the solar neighbourhood from a pilot sample of white dwarf-main sequence binaries
A. Rebassa-Mansergas, B. Anguiano, E. García-Berro +6
The age-metallicity relation (AMR) is a fundamental observational constraint for understanding how the Galactic disc formed and evolved chemically in time. However, there is not ye…
Revisiting the luminosity function of single halo white dwarfs
R. Cojocaru, S. Torres, L. G. Althaus +2
White dwarfs are the fossils left by the evolution of low-and intermediate-mass stars, and have very long evolutionary timescales. This allows us to use them to explore the propert…
DA white dwarfs from the LSS-GAC survey DR1: the preliminary luminosity and mass functions and formation rate
A. Rebassa-Mansergas, X. -W. Liu, R. Cojocaru +9
Modern large-scale surveys have allowed the identification of large numbers of white dwarfs. However, these surveys are subject to complicated target selection algorithms, which ma…
The effects of metallicity on the Galactic disk population of white dwarfs
Ruxandra Cojocaru, Santiago Torres, Jordi Isern +1
It has been known for a long time that stellar metallicity plays a significant role in the determination of the ages of the different Galactic stellar populations, when main sequen…
