Combining outlier analysis algorithms to identify new physics at the LHC
Journal of High Energy Physics, 2021 The lack of evidence for new physics at the Large Hadron Collider so far has prompted the development of model-independent search techniques. In this study, we compare the anomaly scores of a variety of anomaly detection techniques: an isolation forest ...

Mechanical quantum sensing in the search for dark matter [PDF]
Quantum Science and Technology, 2020 Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter.

Journal of High Energy Physics, 2020 Abstract We suggest that an interplay between microscopic and macroscopic physics can give rise to dark matter (DM) whose interactions with the visible sector fundamentally undulate in time, independent of celestial dynamics.

A real triplet-singlet extended Standard Model: dark matter and collider phenomenology
Journal of High Energy Physics, 2021 We examine the collider and dark matter phenomenology of the Standard Model extended by a hypercharge-zero SU(2) triplet scalar and gauge singlet scalar.

The Possibility of Mirror Planet as Planet Nine in the Solar System
Universe, 2022 A series of dynamical anomalies in the orbits of distant trans-Neptunian objects points to a new celestial body (usually named Planet Nine) in the solar system.

Imprints of dark matter on black hole shadows using spherical accretions [PDF]
The European Physical Journal C, 2020 We study the possibility of identifying dark matter in the galactic center from the physical properties of the electromagnetic radiation emitted from an optically-thin disk region around a static and spherically symmetric black hole.

Energy-releasing Process for the 2013 May 13 X1.7 Limb Flare: A Continued Study
The Astrophysical Journal, 2023 In this paper, we reanalyze the X1.7 class limb flare that occurred on 2013 May 13 (SOL2013-05-13T01:56 UT), concentrating on the energy-releasing process using microwave observations mainly made by Nobeyama and X-ray observations made by RHESSI.

One-Minute Quasi-Periodic Pulsations during an M-Class Solar Flare
Universe, 2022 We study the Quasi-Periodic Pulsations (QPPs) of an M4.4 class solar flare, which occurred in active region NOAA 11165 on 8 March 2011. With the Fast Fourier Transform (FFT) method, we decompose the flare light curve into fast- and slowly-varying ...

Fundamental Interactions, 2007 The nature of the main constituents of the mass of the universe is one of the outstanding riddles of cosmology and astro-particle physics. Current models explaining the evolution of the universe, and measurements of the various components of its mass, all have in common that an appreciable contribution to that mass is non-luminous and non-baryonic, and
