Pre-peak Emission in Tidal Disruption Events
The rising part of a tidal disruption event light curve provides unique insight into early emission and the onset of accretion. Various mechanisms are proposed to explain the pre-peak emission, including shocks from debris interaction and reprocessing of disk emission. We study the pre-peak emission and its influence on the gas circularization by a series of gray radiation hydrodynamic simulations with varying black hole mass. We find that given a super-Eddington fallback rate of 10\dot{M}_{Edd…

Washington, DC’s peak cherry bloom is on track to be 10 days ahead of normal #phenology #ClimateChange

So this was quite the late afternoon/evening, so glad I repeated this tour... Took a slightly different route than last year, going up some super craggy canyon for a while (pushing/carrying the bike), but well worth it, especially once up and dipping in the 3rd lake (legs only) en route, snow patches still all around, but air temp in the mid-20s... Another reason this is one of my faves: the last 11km are just rolling downhill (~470 hm).
Some impressions attached (the last pic is of th…

Towards a GPU-Parallelization of the neXtSIM-DG Dynamical Core
The cryosphere plays a significant role in Earth's climate system. Therefore, an accurate simulation of sea ice is of great importance to improve climate projections. To enable higher resolution simulations, graphics processing units (GPUs) have become increasingly attractive as they offer higher floating point peak performance and better energy efficiency compared to CPUs. However, making use of this theoretical peak performance, which is based on massive data parallelism, usually requires mor…

Antarctic sea ice ‘behaving strangely’ as Arctic reaches ‘below-average’ winter peak - Carbon Brief
Antarctic sea ice is “behaving strangely” and might have entered a “new regime”, says director of the US National Snow and Ice Data Centre.

Jamming Intrusions in Extreme Bandwidth Communication: A Comprehensive Overview
As the evolution of wireless communication progresses towards 6G networks, extreme bandwidth communication (EBC) emerges as a key enabler to meet the ambitious key performance indicator set for this next-generation technology. 6G aims for peak data rates of 1 Tb/s, peak spectral efficiency of 60 b/s/Hz, maximum bandwidth of 100 GHz, and mobility support up to 1000 km/h, while maintaining a high level of security. The capability of 6G to manage enormous data volumes introduces heightened securit…

Post-AGB candidate IRAS 02143+5852: Cepheid-like variability, three-layer circumstellar dust envelope and spectral features
We present the results of multicolour $UBVR_{\text{C}}I_{\text{C}}JHK$ photometry, spectroscopic analysis and spectral energy distribution (SED) modelling for the post-AGB candidate IRAS 02143+5852. We detected Cepheid-like light variations with the full peak-to-peak amplitude $ΔV\sim0.9$ mag and the pulsation period of about 24.9 d. The phased light curves appeared typical for the W Vir Cepheids. The period-luminosity relation for the Type II Cepheids yielded the luminosity $\log L/L_{\odot}\…
