TL;DR: The HST ACS Coma Cluster Treasury survey as discussed by the authors was designed to cover an area of 740 arcmin2 in regions of different density of both galaxies and intergalactic medium within the Coma cluster.
Journal ArticleDOI
Mars global simulant MGS-1: A Rocknest-based open standard for basaltic martian regolith simulants
TL;DR: The Mars Global Simulant (MGS-1) as mentioned in this paper is a new standard designed as a high fidelity mineralogical analog to global basaltic regolith on Mars, as represented by the Rocknest windblown deposit at Gale crater.

TL;DR: The HST ACS Coma cluster survey was designed to cover an area of 740 square arcmin in regions of different density of both galaxies and intergalactic medium within the cluster.
Journal ArticleDOI
A displaced supermassive black hole in m87
TL;DR: In this article, a projected displacement of 6.8 +/- 0.8 pc (similar to 0 ''.1) between the nuclear point source (presumed to be the location of the supermassive black hole, SMBH) and the photo-center of the galaxy was found.
Journal ArticleDOI
The nature of the HE0450−2958 system

TL;DR: In this article, the authors test the hypothesis that the black hole powering the quasar was ejected from the companion galaxy during a merger and show that the ejection model is unlikely, since the kick velocity required to remove a black hole from the galaxy is 500 km s −1, inconsistent with the presence of narrow emission-line gas at the same redshift as the quasars nucleus, and the predicted luminosity of the host galaxy is then consistent with the upper limits inferred by those authors.
