We present results from a new cosmological hydrodynamics simulation campaign of protocluster (PC) regions, FOREVER22: FORmation and EVolution of galaxies in...

We present SAURON integral-field observations of the S0 galaxy NGC 7332. Existing broad-band ground-based and Hubble Space Telescope (HST) photometry reveals a...

We perform high-resolution cosmological hydrodynamic simulations to study the formation of the first galaxies that reach the masses of 10 8 - 9 h -1 M ⊙ at z =...

We study ultra-diffuse galaxies (UDGs) in zoom in cosmological simulations, seeking the origin of UDGs in the field versus galaxy groups. We find that while...

We present the first pointed X-ray observations of 10 candidate fossil galaxy groups and clusters. With these Suzaku observations, we determine global...

We report the discovery of four massive (M > 0.8 M⊙) ZZ Ceti white dwarfs, including an ultramassive 1.16 M⊙ star. We obtained ground-based, time series...

To understand the physical processes governing accretion discs we can study active galactic nuclei (AGNs), X-ray binary systems (XRBs), and cataclysmic...

The geometric characteristics of dust clouds provide important information on the physical processes that structure such clouds. One of such characteristics is...

We present a study of a sample of 254 clusters from the SDSS-DR7 Yang Catalogue and an auxiliary sample of field galaxies to perform a detailed investigation on...
