Autor: Tzanavaris, P., Gallagher, S. C., Ali, S., Miller, D. R., Pentinga, S., Johnson, K. E.

Publikováno v: ApJ (2019) 871, 242

We detected 10 compact galaxy groups (CGs) at $z=0$ in the semi-analytic galaxy catalog of Guo et al. (2011) for the milli-Millennium Cosmological Simulation (sCGs in mGuo2010a). We aimed to identify potential canonical pathways for compact group evo

Heavy Element Absorption Systems at $5.0

Autor: Cooper, T. J., Simcoe, R. A., Cooksey, K. L., Bordoloi, R., Miller, D. R., Furezs, G., Turner, M. L., Bañados, E.

Publikováno v: The Astrophysical Journal, Volume 882, Issue 2, article id. 77, 22 pp. (2019)

Ratios of different ions of the same element encode ionization information independently from relative abundances in quasar absorption line systems, crucial for understanding the multiphase nature and origin of absorbing gas, particularly at $z>6$ wh

The identification of z-dropouts in Pan-STARRS1: three quasars at 6.5

Publikováno v: The Astrophysical Journal Letters, Volume 801, Issue 1, article id. L11, 7 pp. (2015)

Luminous distant quasars are unique probes of the high redshift intergalactic medium (IGM) and of the growth of massive galaxies and black holes in the early universe. Absorption due to neutral Hydrogen in the IGM makes quasars beyond a redshift of z
