Recycled Gas Dominates the Metal-rich Fuel of Supermassive Black Holes

Dongyun Kwak, Ena Choi, Hannah Jhee +5

Understanding the origin and chemical properties of gas accreted by supermassive black holes (SMBHs) is essential for linking black hole growth to galaxy evolution. Using a suite o…

The impact of evolving cosmic filaments on mass and spin evolution of dark matter halos

Hannah Jhee, Hyunmi Song, Clotilde Laigle +3

The evolution of galaxies is closely tied to that of their host dark matter halos, which is in turn strongly modulated by the surrounding large-scale environment. Cosmic filaments…

Tracing the AGN-Merger Connection: insights from cosmological simulations and JWST mock observations

Hannah Jhee, Ena Choi, Rachel S. Somerville +6

Galaxy mergers have long been proposed as a mechanism for funneling gas toward galactic centres, potentially triggering accretion onto supermassive black holes (SMBHs) and igniting…

An optimized search for dark matter in the galactic halo with HAWC

A. Albert, R. Alfaro, C. Alvarez +63

The Galactic Halo is a key target for indirect dark matter detection. The High Altitude Water Cherenkov (HAWC) observatory is a high-energy (~300 GeV to >100 TeV) gamma-ray detecto…

A Contribution of the HAWC Observatory to the TeV era in the High Energy Gamma-Ray Astrophysics: The case of the TeV-Halos

Ramiro Torres-Escobedo, Hao Zhou, Eduardo de la Fuente +130

We present a short overview of the TeV-Halos objects as a discovery and a relevant contribution of the High Altitude Water Čerenkov (HAWC) observatory to TeV astrophysics. We discu…

Tracking Halo Orbits and Their Mass Evolution around Large-scale Filaments

Hannah Jhee, Hyunmi Song, Rory Smith +3

We have explored the dynamical and mass evolution of halos driven by large-scale filaments using a dark matter-only cosmological simulation with the help of a phase-space analysis.…

Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

Celine Armand, Eric Charles, Mattia di Mauro +13

Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challengi…

Particle Acceleration in the Cygnus Superbubble

B. Hona

The Cygnus Cocoon is the first gamma-ray superbubble powered by a massive stellar association, the OB2 association. It was postulated that the combined effects of the stellar winds…

The all-particle cosmic ray energy spectrum measured with HAWC

J. A. Morales-Soto, J. C. Arteaga-Velázquez

Thanks to recent technological development, a new generation of cosmic ray experiments have been developed with more sensitivity to study these particles in the primary energy inte…

Monitoring the radio galaxy M87 with HAWC

T. Capistrán, D. Avila Rojas, M. M. González +2

Studies of radio galaxies at TeV energies are fascinating because their jets are misaligned concerning our sightline. Thus, it provides us with a unique opportunity to study the st…

Use of Machine Learning for gamma/hadron separation with HAWC

T. Capistrán, K. L. Fan, J. T. Linnemann +3

Background showers triggered by hadrons represent over 99.9% of all particles arriving at ground-based gamma-ray observatories. An important stage in the data analysis of these obs…

Horizontal muon track identification with neural networks in HAWC

J. R. Angeles Camacho, H. León Vargas

Nowadays the implementation of artificial neural networks in high-energy physics has obtained excellent results on improving signal detection. In this work we propose to use neural…

Combined Dark Matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, HESS, MAGIC and VERITAS

Louise Oakes, Celine Armand, Eric Charles +13

The search for Dark Matter (DM) has great potential to reveal physics beyond the Standard Model. As such, searches for evidence of DM particles are being carried out using a wide r…
