Direct photons are produced at every stage of the nucleus-nucleus collision and therefore they are sensitive to the different phases of the medium evolution. The low-$p_T$ component of the direct photon spectrum is dominated by thermal production in the quark-gluon plasma and during the hadron-gas phase and carries information about the temperature of the emitting medium; for $p_T$ greater...

photons in Au+Au collisions at 200 GeV compared to reference p+p
collisions, which has been attributed to thermal radiation from the
medium produced in the collisions. At the same time the excess photons
show a large azimuthal anisotropy, expressed as Fourier coefficients
v2 and v3. These surprising results have not

A primary goal of heavy ion physics is to study the fundamental properties of the hot and dense medium created in the ultra-relativistic heavy-ion collisions. The hot, dense medium is expected to emit thermal radiation in the form of direct photons and dileptons. Once produced, photons traverse the medium with minimum interactions. This makes photons an ideal probe of the medium evolution by...

We present a systematic study of electromagnetic radiation and of the hadronic observables in (p, d, $^3$He)+Au collisions at RHIC energies and in p+Pb collisions at the LHC energy. Using a (3+1)-d viscous hydrodynamics + hadronic cascade hybrid framework, the effects of breaking the longitudinal boost-invariance on direct photon and hadronic observables are quantified. Predictions of thermal...

Bulk viscosity has recently been shown to play a major role in describing both photon [1] and hadron [2] observables at the Relativistic Heavy-Ion Cllider (RHIC) and the Large Hadron Collider (LHC). Thermal dilepton production is a particularly interesting electromagnetic probe that, up until now, has not been studied within such simulations. Using the differential nature of the dilepton...
