Abstract: We have discovered a 300 kpc-wide giant Lyman-α (Lyα) nebula centered on the massive galaxy group RO-1001 at z = 2.91 in the Cosmic Evolution Survey field. Keck Cosmic Web Imager observations reveal three cold… read more here.

DOI: 10.1093/mnras/stx1243
Abstract: We present accurate photometric redshifts for galaxies observed by the Cluster Lensing And Supernova survey with Hubble (CLASH). CLASH observed 25 massive galaxy cluster cores with the Hubble Space Telescope in 16 filters spanning 0.2–1.7… read more here.

DOI: 10.1093/mnras/sty2533
Abstract: We identify a sample of 1959 massive clusters of galaxies in the redshift range of 0.7 0.75. By comparing them with clusters at lower redshifts, we confirm that richer clusters host more luminous brightest cluster… read more here.

DOI: 10.1093/mnras/sty598
Abstract: A number of merging galaxy clusters shows the presence of shocks and cold fronts, i.e. sharp discontinuities in surface brightness and temperature. The observation of these features requires an X-ray telescope with high spatial resolution… read more here.

DOI: 10.1126/science.abj9192
Abstract: Stars form in galaxies, from gas that has been accreted from the intergalactic medium. Simulations have shown that recycling of gas—the reaccretion of gas that was previously ejected from a galaxy—could sustain star formation in… read more here.
