The future of astronomy with small satellites [PDF]
Nature Astronomy volume 4, pages 1031-1038 (2020), 2020 The number of small satellites has grown dramatically in the past decade from tens of satellites per year in the mid-2010s to a projection of tens of thousands in orbit by the mid-2020s. This presents both problems and opportunities for observational astronomy.

Very High Energy Gamma‐Ray Astronomy [PDF]
Publications of the Astronomical Society of the Pacific, 1999 We present a review of the current status of very high energy gamma-ray astronomy. The development of the atmospheric Cherenkov imaging technique for ground-based gamma-ray astronomy has led to a rapid growth in the number of observatories. The detection of TeV gamma rays from Active Galactic Nuclei was unexpected and is providing new insights into the

An analytic analysis of the pion decay constant in three-flavoured chiral perturbation theory
European Physical Journal C: Particles and Fields, 2017 A representation of the two-loop contribution to the pion decay constant in SU(3) chiral perturbation theory is presented. The result is analytic up to the contribution of the three (different) mass sunset integrals, for which an expansion in their ...

Multi-messenger astronomy with very-high-energy gamma-ray observations [PDF]
Journal of Physics: Conference Series, 2019 After decades of development, multi-messenger astronomy, the combination of information on cosmic sources from photons, neutrinos, charged particles and gravitational waves, is now an established reality.

From gamma-ray bursts to fast radio bursts [PDF]
Nature Astronomy, volume 2, 832-835 (2018), 2018 The field of gamma-ray burst astronomy arguably went through three decades of growing pains before reaching maturity. What development lessons can be learned for the adolescent field of fast radio burst astronomy?

High-Energy Neutrino Astronomy: Current Status and Prospects [PDF]
Proceedings of European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2019), 2019 In the last decade, neutrino astronomy has taken off with two major breakthroughs, the first observation of high-energy astrophysical neutrinos in 2013 and the first evidence for gamma-rays and neutrinos from a single object published in summer 2018.

Astrophotonics: the rise of integrated photonics in astronomy [PDF]
Optics & Photonics News (2019), 2019 Astronomers have come to recognize the benefits of photonics, often in combination with optical systems, in solving longstanding experimental problems in Earth-based astronomy. Here, we explore some of the recent advances made possible by integrated photonics. We also look to the future with a view to entirely new kinds of astronomy, particularly in an

Physics Letters B, 2021 We perform a study of W-boson production in polarized proton-proton collisions through next-to-next-to-leading order (NNLO) in perturbative QCD. This calculation is required to extend the extraction of polarized parton distribution functions to NNLO ...

Rényi divergences from Euclidean quenches
Journal of High Energy Physics, 2020 We study the generalisation of relative entropy, the Rényi divergence D α (ρ∥ρ β ) in 2d CFTs between an excited state density matrix ρ, created by deforming the Hamiltonian, and the thermal density matrix ρ β .
