The peculiar hard state behaviour of the black hole X-ray binary Swift J1727.8$-$1613
Tracking the correlation between radio and X-ray luminosities during black hole X-ray binary outbursts is a key diagnostic of the coupling between accretion inflows (traced by X-rays) and relativistic jet outflows (traced by radio). We present the radio--X-ray correlation of the black hole low-mass X-ray binary Swift~J1727.8$-$1613 during its 2023--2024 outburst. Our observations span a broad dynamic range, covering $\sim$4 orders of magnitude in radio luminosity and $\sim$6.5 in X-ray luminosi…

For #MusicWomenWednesday this week, a killer new find-- Melbourne, Australia's PHANTASM. Some really ripping hardcore punk here highlighted by the raw, furious vocals of Bernadette Fitzgibbon. Stumbled across this 4 song 7" EP 'Conflict Reality' that Phantasm put out in 2023 via Hardcore Victim, and I've really been digging it this week.

Comprehensive Radio Monitoring of the Black Hole X-ray Binary Swift J1727.8$-$1613 during its 2023$-$2024 Outburst
This work presents comprehensive multi-frequency radio monitoring of the black hole low-mass X-ray binary Swift J1727.8$-$1613, which underwent its first recorded outburst after its discovery in August 2023. Through a considerable community effort, we have coalesced the data from multiple, distinct observing programs; the light curves include ${\sim} 10$ months and 197 epochs of monitoring from 7 radio facilities with observing frequencies ranging from (approximately) 0.3$-$230GHz. The primary …

Evolution of QPO During Discovery Outburst of MAXI J1834-021: Estimation of Intrinsic Parameters from Spectro-Temporal Study
The Galactic transient black hole candidate (BHC) MAXI~J1834-021 was detected for the first time by MAXI/GSC on February 05, 2023 and it was active for next $\sim 10$~months. A monotonic evolution of low-frequency QPOs from higher to lower frequencies is observed in the middle-phase of the outburst. We study this evolution of the QPO with the propagating oscillatory shock (POS) model, and it suggests the presence of a receding shock. The POS model fit also estimates the mass of the source to be…

A Tale of Two Shocks
It was the best of times, it was the worst of times, . . . - for the thermal/suprathermal particle populations in the vicinity of two traveling interplanetary shocks observed by Solar Orbiter on 2023-11-29 07:51:17 UTC and 2023-11-30 10:47:26 UTC at $\sim 0.83$ astronomical units from the Sun. We investigate these two very dissimilar shocks and elucidate their non-equilibrium features. We do not provide explanations of all observed features, our aim is to report them here for future reference…

X-ray Polarization Detection of the Pulsar Wind Nebula in G21.5-0.9 with IXPE
We present the X-ray polarization observation of G21.5-0.9, a young Galactic supernova remnant (SNR), conducted with the Imaging X-ray Polarimetry Explorer (IXPE) in October 2023, with a total livetime of approximately 837 ks. Using different analysis methods, such as a space-integrated study of the entire region of the PWN and a space-resolved polarization map, we detect significant polarization from the pulsar wind nebula (PWN) at the center of the SNR, with an average polarization degree of …

Gaming the Metrics? Bibliometric Anomalies and the Integrity Crisis in Global University Rankings
Global university rankings have transformed how certain institutions define success, often elevating metrics over meaning. This study examines universities with rapid research growth suggestive of metric-driven behaviors. Among the 1,000 most publishing institutions, 98 showed extreme output increases between 2018-2019 and 2023-2024. Of these, eighteen were selected for exhibiting sharp declines in first and corresponding authorship. Compared to national, regional, and international norms, thes…
