Parallel Hierarchical Agglomerative Clustering in Low Dimensions
Hierarchical Agglomerative Clustering (HAC) is an extensively studied and widely used method for hierarchical clustering in $\mathbb{R}^k$ based on repeatedly merging the closest pair of clusters according to an input linkage function $d$. Highly parallel (i.e., NC) algorithms are known for $(1+ε)$-approximate HAC (where near-minimum rather than minimum pairs are merged) for certain linkage functions that monotonically increase as merges are performed. However, no such algorithms are known for…

Discovery of 146.8 s pulsations from EP J005146.9-730930, a new transient Be/X-ray binary in the SMC
Recent observations of the Small Magellanic Cloud (SMC) with Einstein Probe (EP) revealed a new transient X-ray source, most likely identified as Be/X-ray binary. To characterise the X-ray properties of EP J005146.9-730930 and in particular to look for pulsations in the X-ray flux, we triggered an XMM-Newton anticipated target of opportunity observation. To follow the flux evolution during the outburst we monitored the source for about three months with the Follow-up X-ray Telescope of EP. The …

Time-resolved p-mode oscillations for subgiant HD 142091 with NEID at WIYN
Detections of Earth-analog planets in radial velocity observations are limited by stellar astrophysical variability occurring on a variety of timescales. Current state-of-the-art methods to disentangle potential planet signals from intrinsic stellar signals assume that stellar signals introduce asymmetries to the line profiles that can therefore be separated from the pure translational Doppler shifts of planets. Here, we examine this assumption using a time series of resolved stellar p-mode osc…

Cloudflare 1.1.1.1 Incident on July 14, 2025
On July 14th, 2025, Cloudflare made a change to our service topologies that caused an outage for 1.1.1.1 on the edge, resulting in downtime for 62 minutes for customers using the 1.1.1.1 public DNS Resolver as well as intermittent degradation of service for Gateway DNS. We’re deeply sorry for this outage. This outage was the result of an internal configuration error and not the result of an attack or a BGP hijack. In this blog post, we’re going to talk about what the failure was, why it o…

Discovery of a transiting hot water-world candidate orbiting Ross 176 with TESS and CARMENES
The case of Ross 176 is a late K-type star that hosts a promising water-world candidate planet. The star has a radius of $R_*$=0.569$\pm$0.020$R_{\odot}$ and a mass of $M_{\star}$ = 0.577 $\pm$ 0.024 $M_{\odot}$. We constrained the planetary mass using spectroscopic data from CARMENES, an instrument that has already played a major role in confirming the planetary nature of the transit signal detected by TESS. We used Gaussian Processes (GP) to improve the analysis because the host star has a re…

$^{50}$Cr and $^{53}$Cr neutron capture cross sections measurement at the n_TOF facility at CERN
$^{50,53}$Cr are very relevant in criticality safety benchmarks related to nuclear reactors. The discrepancies between the neutron capture cross section evaluations have an important effect on the $k_{eff}$ and $k_{\infty}$ in criticality benchmarks particularly sensitive to chromium. The $^{50,53}$Cr(n,$γ$) cross sections is to be determined between 1 and 100 keV with an 8-10% accuracy following the requirements of the NEA High Priority Request List (HPRL) to solve the current discrepancies. …

Stromausfälle nach russischem Luftangriff auf Krywyj Rih
In der südostukrainischen Großstadt Krywyj Rih ist es nach russischen Angriffen mit Drohnen und mindestens einer Rakete zu Stromausfällen gekommen. "Es gab etwa 20 Einschläge", teilte der Militärverwaltungschef Olexander Wilkul bei Telegram mit. Die Wasserversorgung werde auf Generatoren umgestellt. Er warnte vor nicht ausreichendem Wasserdruck in höheren Etagen.

Sometimes they come back: pulsations in A 0538-66 at 69 ms rediscovered with NICER
We report on NICER X-ray observations of the Be X-ray binary A 0538-66 located in the Large Magellanic Cloud. Fast pulsations (69 ms) in this source were discovered in 1980 during a bright outburst in which it reached a luminosity of ~8E38 erg/s, but were never reobserved since then. We clearly detected the pulsations at P=69.3055 +/- 0.0005 ms with a pulsed fraction of ~20% during a short time interval (~11 minutes) on 2023 January 9, when A 0538-66 had a luminosity of ~8E36 erg/s (0.3-10 keV)…
