Multi-frame DVC for temporal image sequences
Frontiers in Materials, 2022 Digital volume correlation (DVC) is a 3D image-based technique for displacement and strain computation. Traditionally, both (digital image correlation) DIC and DVC are methods based on two individual time frames; the estimation of the displacement and ...

Gas Sloshing and Cold Fronts in Pre-merging Galaxy Cluster A98
The Astrophysical Journal, 2023 We present deep Chandra observations of the pre-merger galaxy cluster Abell 98 (A98). A98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are merging along the north–south direction, A98S is undergoing a separate ...

Multiwavelength Astronomy and CTA: X-rays [PDF]
Astroparticle Physics, 2013 We discuss how future X-ray instruments which are under development can contribute to our understanding of the non-thermal Universe. Much progress has been made in the field of X-ray Astronomy recently, thanks to the operation of modern X-ray telescopes such as Chandra, XMM-Newton, Suzaku, and Swift, but more in-depth investigation awaits future ...

Magnetic Activity–Rotation–Age–Mass Relations in Late-pre-main-sequence Stars
The Astrophysical Journal, 2023 We study the four-dimensional relationships between magnetic activity, rotation, mass, and age for solar-type stars in the age range 5–25 Myr. This is the late-pre-main-sequence (l-PMS) evolutionary phase when rapid changes in a star's interior may lead ...

On the universal X-ray luminosity function of binary X-ray sources in galaxies [PDF]
Astron.Lett. 29 (2003) 372-373, 2002 The empirically determined universal power-law shape of X-ray luminosity function of high mass X-ray binaries in galaxies is explained by fundamental mass-luminosity and mass-radius relations for massive stars.
