Kavli Affiliate: Salman Habib| First 5 Authors: Cooper Jacobus, Cooper Jacobus, , , | Summary:The next generation of cosmological spectroscopic sky surveys will probe the distribution of matter across several Gigaparsecs (Gpc) or many billion light-years. In order to leverage the rich data in these new maps to gain a better understanding of the physics […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Pouya M. Kouch, Ioannis Liodakis, Francesco Fenu, Haocheng Zhang, Stella Boula | Summary: The X-ray polarization observations made possible with the Imaging X-ray Polarimetry Explorer (IXPE) offer new ways of probing high-energy emission processes in astrophysical jets from blazars. Here we report on the first X-ray […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Gregory Gabadadze, David N. Spergel, Giorgi Tukhashvili, , | Summary: We study inflation in a recently proposed gravitational effective field theory describing the trace anomaly. The theory requires an additional scalar which is massless in the early universe. This scalar — referenced as an anomalyon — […]

Kavli Affiliate: Emil Martinec | Summary:An effective action for NS5-branes coupled to supergravity is used to derive the full 10d form of horizon-free BPS solutions of fivebranes carrying momentum waves, including both transverse scalar and internal gauge excitations of the branes. When internal modes are highly excited, we find solutions that plausibly mediate the transition […]
