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...

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...

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.

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 real-time data processing and recent astrophysical results...

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...

Advancing neutrino astronomy depends upon detecting many types of neutrino sources and making connections between them. Here I discuss challenges in supernova neutrino detection and how addressing them benefits the larger field.

The IceCube Neutrino Observatory has been successfully operating for 15 years at the South Pole. During this time, IceCube has made many groundbreaking observations in neutrino astrophysics, including the discovery of a high-energy astrophysical neutrino flux; the Seyfert galaxy NGC1068 as a neutrino source candidate; and neutrinos from the Milky Way.

The KM3NeT collaboration is constructing two neutrino telescope infrastructures in the Mediterranean Sea, ORCA for GeV-energy neutrinos, and ARCA for neutrinos with multi-TeV energies. In this presentation the progress of both infrastructures is discussed, as well as the outlook for completion. Via the path of data acquisition, data quality assessment, calibration and reconstruction, some...

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...
