Search for Ultra-Relativistic Magnetic Monopoles with LHAASO-KM2A

Zhen Cao, F. Aharonian, Y. X. Bai +335

Ultra-relativistic magnetic monopoles traversing the atmosphere are expected to initiate extensive air showers characterized by a muon deficit and a compact lateral profile. Using…

Extreme PeV accelerator associated with GRS 1915+105

Zhen Cao, F. Aharonian, Y. X. Bai +322

Microquasars, binary systems featuring relativistic jets, have emerged as sources for particle acceleration beyond PeV energies. We present a study of the broadband -ray emissio…

Ultra-high-energy -ray imprints from PeV particles accelerated by supernova remnants

Zhen Cao, F. Aharonian, Y. X. Bai +320

The quest for the origin of cosmic ray (CRs) is a fundamental issue in astrophysics. Shocks of supernova remnants (SNRs) have been considered as the dominant contributors to Galact…

Search for TeV emission from spider millisecond pulsars with HAWC

R. Alfaro, E. Anita-Rangel, M. Araya +90

Millisecond pulsars (MSPs) are observed to emit multi-wavelength radiation, from radio to GeV. Spider MSPs, which interact with their low-mass companion in close orbit (orbital per…

A Multi-messenger Search for Ultra-high-energy Gamma Rays in Coincidence with Neutrinos

R. Alfaro, C. Alvarez, A. Andrés +101

The last five years have shown us that ultra-high-energy (UHE; 100 TeV) gamma-ray sources are ubiquitous, but the nature of these sources remain highly uncertain. UHE gamma rays…

LHAASO observation of Mrk 421 during 2021 March - 2024 March: a comprehensive VHE catalog of multi-timescale outbursts and its time average behavior

The LHAASO Collaboration, Zhen Cao, F. Aharonian +321

The Large High Altitude Air Shower Observatory (LHAASO) monitors sources within its field of view for up to 7 hours daily, achieving a duty cycle exceeding 98% and an annual point-…

Investigating IceCube Neutrino Alerts with the HAWC -Ray Observatory

The HAWC Collaboration, R. Alfaro, C. Alvarez +95

Neutrino emission from astrophysical sources has long been considered a signature of cosmic-ray acceleration. The IceCube neutrino observatory has observed a diffuse flux of TeV-Pe…

Transient Large-Scale Anisotropy in TeV Cosmic Rays due to an Interplanetary Coronal Mass Ejection

Zhen Cao, F. Aharonian, Y. X. Bai +309

Large- or medium-scale cosmic ray anisotropy at TeV energies has not previously been confirmed to vary with time. Transient anisotropy changes have been observed below 150 GeV, esp…
