PublicaciónThe Unrelaxed Dynamical Structure of the Galaxy Cluster Abell 85
For the first time, we explore the dynamics of the central region of a galaxy cluster within r 500 ∼ 600 h‑1 kpc from its center by combining optical and X-ray...

PublicaciónThe unseen population of F- to K-type companions to hot subdwarf stars
We present a method to select hot subdwarf stars with A- to M-type companions using photometric selection criteria. We cover a wide range in wavelength by...

PublicaciónThe Unusual Vertical Mass Distribution of NGC 4013 Seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G)
NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" H I warp and its "giant" tidal stream. Previous work on this unusual object shows that it...
