DOI: 10.1007/s11430-018-9311-y
Abstract: The correlation between atmospheric gravity waves (GWs) and Transient Luminous Events (TLEs) has been poorly studied using both synchronous observations and numerical simulations. To investigate the modulation effects of GWs on TLEs, a troposphere-mesosphere quasi-electrostatic… read more here.

DOI: 10.1088/1475-7516/2022/09/026
Abstract: We consider gamma-ray signals of dark matter annihilation in extragalactic halos in the case where dark matter annihilates from a p-wave or d-wave state. In these scenarios, signals from extragalactic halos are enhanced relative to… read more here.

DOI: 10.1093/mnras/staa2394
Abstract: We examine X-ray scaling relations for massive halos ($M_{500}>10^{12.3}M_\odot$) in the Simba galaxy formation simulation. The X-ray weighted luminosity, $L_X$ vs. $M_{500}$ has power-law slopes $\approx\frac{5}{3}$ and $\approx\frac{8}{3}$ above and below $10^{13.5} M_{\odot}$, deviating from… read more here.

DOI: 10.1093/mnras/stad1396
Abstract: Feedback driven by jets from active galactic nuclei is believed to be responsible for reducing cooling flows in cool-core galaxy clusters. We use simulations to model feedback from hydrodynamic jets in isolated halos. While the… read more here.

DOI: 10.1103/physrevd.107.083010
Abstract: Milky Way (MW) satellites exhibit a diverse range of internal kinematics, reflecting in turn a diverse set of subhalo density profiles. These profiles include large cores and dense cusps, which any successful dark matter model… read more here.

Abstract: Observations by HAWC and Milagro have detected bright and spatially extended TeV $\ensuremath{\gamma}$-ray sources surrounding the Geminga and Monogem pulsars. We argue that these observations, along with a substantial population of other extended TeV sources… read more here.
