Collider and CMB complementarity of leptophilic dark matter with light Dirac neutrinos by Debasish Borah, Nayan Das, Sahabub Jahedi, Bhavya Thacker

“…The right chiral parts of light Dirac neutrinos get thermalised due to their interactions with the bath as well as leptophilic DM, leading to enhanced effective relativistic degrees of freedom N eff within reach of future cosmic microwave background (CMB) experiments. The interplay of existing bounds from cosmological observations related to DM relic and N eff, direct and indirect detection of DM, astrophysics, and collider observations leave promising discovery prospects at future electron and muon colliders along with complementary signatures at future CMB experiments.…”

Primordial Magnetic Field Effects on the CMB and Large-Scale Structure by Dai G. Yamazaki, Kiyotomo Ichiki, Toshitaka Kajino, Grant J. Mathews

“…Such a primordial magnetic field (PMF) would be expected to manifest itself in the cosmic microwave background (CMB) temperature and polarization anisotropies, and also in the formation of large-scale structure. …”

FastEEC: Fast evaluation of N-point energy correlators by Ankita Budhraja, Wouter J. Waalewijn

“…This view of collisions is akin to analyzes of the Cosmic Microwave Background, and a range of promising phenomenological applications of energy correlators have been identified, including the study of hadronization, the deadcone effect, measuring αs and the top quark mass. …”

Monster Radio Jet (>66 kpc) Observed in Quasar at z ∼​​​​​ 5 by Anniek J. Gloudemans, Frits Sweijen, Leah K. Morabito, Emanuele Paolo Farina, Kenneth J. Duncan, Yuichi Harikane, Huub J. A. Röttgering, Aayush Saxena, Jan-Torge Schindler

“…These large radio lobes have been argued to remain elusive at z  > 4 due to energy losses in the synchrotron emitting plasma as a result of scattering of the strong cosmic microwave background at these high redshifts. Nonetheless, the 0 $\mathop{.}…”
