Are fossil groups a challenge of the Cold Dark Matter paradigm?
Stefano Zibetti, Daniele Pierini, Gabriel W. Pratt
We study six groups and clusters of galaxies suggested in the literature to be `fossil' systems (i.e. to have luminous diffuse X-ray emission and a magnitude gap of at least 2 mag-…
GRB 080913 at redshift 6.7
J. Greiner, T. Kruehler, J. P. U. Fynbo +44
We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND which led to the discovery of its optical/NIR afterglow and…
Diffuse stellar emission in X-ray luminous galaxy clusters at z~0.3 I. Is the diffuse optical light boosted and rejuvenated in merging clusters?
D. Pierini, S. Zibetti, F. Braglia +4
[Abridged] We searched for diffuse stellar emission around BCGs in three of the most X-ray luminous clusters found at z~0.3 in the REFLEX cluster survey and observed with XMM-Newto…
Unveiling the Important Role of Groups in the Evolution of Massive Galaxies: Insights from an Infrared Passive Sequence at Intermediate Redshift
D. J. Wilman, D. Pierini, K. Tyler +6
The most massive galaxies in the Universe are also the oldest. To overturn this apparent contradiction with hierarchical growth models, we focus on the group scale haloes which hos…
Presence of dust with a UV bump in massive, star-forming galaxies at 1 < z < 2.5
S. Noll, D. Pierini, M. Pannella +1
Fundamental properties of the extinction curve, like the slope in the rest-frame ultraviolet (UV) and the presence/absence of a broad absorption excess centred at 2175 A (the UV bu…
Flaming, bright galaxies along the filaments of A2744
Filiberto Braglia, Daniele Pierini, Hans Böhringer
The existence of a clumpy, large-scale filamentary structure is at the basis of the current paradigm of cosmic formation and evolution of clusters. The star-formation history of ga…
