New Frontiers in Cosmology and Galaxy Formation: Challenges for the Future
Richard Ellis, Joseph Silk
(Abridged) Cosmology faces three distinct challenges in the next decade. (1) The dark sector, both dark matter and dark energy, dominates the Universe. Key questions include determ…
Recent star formation in high-redshift early-type galaxies: insights from the rest-frame UV
S. Kaviraj, S. K. Yi, E. Gawiser +4
We combine deep UBVRIzJK photometry from the MUSYC survey with redshifts from the COMBO-17 survey to study the rest-frame ultraviolet (UV) properties of 674 high-redshift (0.5<z<1)…
Secondary anisotropies of the CMB
Nabila Aghanim, Subhabrata Majumdar, Joseph Silk
The Cosmic Microwave Background fluctuations provide a powerful probe of the dark ages of the universe through the imprint of the secondary anisotropies associated with the reionis…
The role of minor mergers in the recent star formation history of early-type galaxies
Sugata Kaviraj, Sebastien Peirani, Sadegh Khochfar +2
We demonstrate that the large scatter in the ultra-violet (UV) colours of intermediate-mass early-type galaxies in the local Universe and the inferred low-level recent star formati…
Hydrostatic equilibrium of a porous intracluster medium: implications for mass fraction and X-ray luminosity
Adi Nusser, Joe Silk
The presence of dilute hot cavities in the intracluster medium (ICM) at the cores of clusters of galaxies changes the relation between gas temperature and its X-ray emission proper…
Solving the cosmic lithium problems with primordial late-decaying particles
Daniel Cumberbatch, Kazuhide Ichikawa, Masahiro Kawasaki +3
We investigate the modifications to predictions for the abundances of light elements from standard Big-Bang nucleosynthesis when exotic late-decaying particles with lifetimes excee…
