The Imaging Atmospheric Cherenkov technique has proved to be an extraordinarily successful approach to gamma-ray astronomy from the ground, covering the energy range from tens of GeV to 100 TeV with exceptional background discrimination, instantaneous sensitivity, and angular and energy resolution. The field is extremely active, with observations that address a wide range of topics; from the...

This year marks the 18th launch anniversary of the Fermi Gamma-ray Space Telescope. The Fermi era has opened up access to the GeV gamma-ray sky and enabled science discoveries across a wide range of astronomical phenomena, including white dwarfs, neutron stars, black holes and their energetic activities. With that progress, the field continues to work on big questions about the origins of...

This talk will cover the analysis of cosmic neutrinos and recent results from the IceCube Neutrino Observatory. We go over measurements of the astrophysical neutrino spectrum and what this reveals about the dynamics of their sources in cosmic ray accelerators. We will also investigate specific neutrino sources, including the Milky Way.

Anna Suliga and I have been modeling the Pierre Auger Observatory spectrum and composition data in the Binary Neutron Star Merger scenario, including interactions in the source and acceleration in both jet and magnetized outflow. Our results provide strong evidence that UHECRs are produced in binary neutron star mergers. We show how UHECRs and UHE-neutrinos elucidate otherwise inaccessible...

Pulsar timing array experiments around the world have found evidence of nanohertz gravitational waves in the form of a stochastic gravitational wave background. This discovery opens another window on the gravitational wave universe that we can use to study a variety of astrophysical and cosmological sources, as well as perform tests of gravity. Pulsar timing arrays search for gravitational...

Over the next several years, more sensitive measurements of the polarization anisotropy of the cosmic microwave background (CMB) are poised to lead to substantial improvements in cosmological constraints. On degree angular scales, the amplitude of the B-mode polarization gives a constraint on the energy scale of cosmic Inflation, with measurements in the next several years improving...

The Baikal-GVD neutrino telescope is a large-scale underwater detector designed for the study of high-energy cosmic neutrinos and their astrophysical sources. The detector is being continuously expanded in Lake Baikal and is approaching a cubic-kilometer sensitive volume. We present the current status of the telescope, including ย real-time data processing and recent astrophysical results...

The High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory in the high mountains of Mexico has accumulated more 10 years of data and has recently completed a re-analysis of our data giving us significant improvements in our low energy response, angular resolution, background rejection and an expanded field of view. This talk will present an overview of these recent HAWC results showing...

KM3NeT/ARCA is a deep-sea neutrino telescope currently under construction in the Mediterranean Sea, designed to investigate high-energy cosmic neutrinos and their sources. Already collecting data with a partial configuration, KM3NeT/ARCA is producing results in neutrino astronomy. This talk will review the latest astrophysical results, including searches for diffuse emission and cosmic...

The majority of multi-messenger observations that combine X-rays and neutrinos to target transient objects have been restricted to reporting flux upper limits, yielding minimal physical insights. We hereby propose a novel analytical method that integrates a generic cosmic-ray and neutrino emission model with unspecified physical parameters and a novel data analysis approach, which enables the...

The highest energy astrophysical and cosmogenic neutrinos still await discovery, and allow us to understand the most energetic cosmic accelerators in the universe. I will discuss the status, plans, and highlight recent results from experiments that aim to detect the highest energy neutrinos, focusing on instruments that look for radio emission from in-ice interactions from UHE neutrinos. I...

Over the past decade, measurements of the cosmic-ray flux and mass composition have improved dramatically, from direct detection in space to giant air-shower arrays. This raises a simple question: do the data from many experiments, using very different techniques, add up to one consistent picture? We address it with a global fit of the spectrum and composition, from GeV energies to the highest...

High-energy neutrinos produced in collisions of protons in the atmosphere or near the vicinity of black holes bring unique opportunities to probe fundamental physics. The unprecedented energy ranges and distance traversed by these neutrinos have enabled the IceCube Neutrino Observatory to search for low-energy signatures of quantum gravity and new neutrino phenomena. In this colloquium, I will...
