The age of the Ursa Major moving group has been assessed from the ages of its members, including nuclear member Merak (β UMa), an A1-type subgiant, by comparing effective temperature and luminosity constraints to model stellar evolution tracks. Previous interferometric limb-darkened angular diameter measurements of β UMa inthe near-infrared (CHARA Array, 1.149 ± 0.014 mas) and mid-infrared...
I will present the current status of the work done by our "Intensity Interferometry at Calern" (I2C) consortium in Nice (France) on the revival of intensity interferometry with optical telescopes.
In short, we have demonstrated intensity correlations using stellar light for the first time in the photon-counting regime, using 1m-class telescopes at Calern Observatory. We have then dedicated...
Astronomical HBT interferometry is simultaneously just like femtoscopy and yet as different as can be. Perhaps one can think of astronomical HBT interferometry (or intensity interferometry) as probing (transverse) momentum on scales of nano eV/c by measuring particle correlations on scales of hundreds of metres.
This talk will try to make the connection, present some new results on massive...
Signs of collectivity were initially seen in AuAu collisions at RHIC through measurements of two-particle long-range correlations in (pseudorapidity) Δη, within small (azimuthal) Δφ angles. In addition, in 2010 a similar ridge-like behavior was observed in high multiplicity proton-proton (pp) collisions at 7 TeV at the LHC by CMS, extended afterwards also to pPb and PbPb collisions. Several...
Over recent decades, substantial attention has been directed toward the characteristics of hyperons in dense matter, particularly in the context of stars. Energetically, hyperons might exist in the inner layers of neutron stars, where the structural arrangement is notably influenced by the equation of state (EOS) describing nuclear matter at densities exceeding saturation. The inclusion of...
Particle correlations are a powerful tool to study the properties of the bulk nu-
clear matter produced in relativistic heavy ion collisions. The momentum cor-
relations between identical particles originating from the same particle-emitting
source, referred to as the Bose-Einstein correlations, measure scales that are
related to the geometrical size of the source. The two-particle...
Many recent measurements in small collision systems such as pp and p–-Pb collisions show signs of collective behavior of produced particles. The two-particle number and transverse momentum (differential) correlators and charged-particle balance function measurements in Pb--Pb collisions provided valuable information about the particle production mechanisms and their time evolution as well as...
