We study luminosity and morphology segregation of cluster galaxies in an ensemble cluster built from 59 rich, nearby galaxy clusters observed in the ESO Nearby Cluster Survey (ENACS). The ensemble cluster contains 3056 member galaxies with positions, velocities and magnitudes ; 96% of these also have galaxy types. From positions and velocities we identify galaxies within substruc-tures, viz. as...
A selection of new jet substructure measurements are reported from the ALICE experiment at CERN LHC in both proton-proton and heavy-ion collisions. These include first fully corrected inclusive groomed momentum fraction radius, as well $$N$$ -subjettiness distribution fragmentation reclustered subjets. We also report on measurement several observables heavy-flavor jets pp collisions, functions ...
We study how gravitational focusing (GF) of dark matter by the Sun affects the annual and biannual modulation of the expected signal in non-directional direct dark matter searches, in the presence of dark matter substructure in the local dark halo. We consider the Sagittarius stream and a possible dark disk, and show that GF suppresses some, but not all, of the distinguishing features that woul...
1.1. Standard Equilibrium and the Algorithm. This is the theorem with which we ended the previous lecture: Theorem 1. There exists δ∗ ∈ (0, 1) such that for all δ ∈ (δ∗, 1), any standard equilibrium must be of the following form. At a stage in which any substructure π has left the game (with associated numerical substructure n), the next coalition that forms is of size t(n) and the payoff to a ...
Dark matter annihilation in Galactic substructure produces diffuse gamma-ray emission of remarkably constant intensity across the sky, and in general this signal dominates over the smooth halo signal at angles greater than a few tens of degrees from the Galactic Center. The large-scale isotropy of the emission from substructure suggests that it may be difficult to extract this Galactic dark mat...
