Irony at z=6.68: a bright AGN with forbidden Fe emission and multi-component Balmer absorption
We present the deepest medium-resolution JWST/NIRSpec spectroscopy to date of a bright Little Red Dot (LRD) AGN, Irony at z=6.68. The data reveal broad Balmer emission from H$α$-H$δ$ and Balmer absorption in H$α$-H$ε$. The absorption lines are kinematically split: H$α$ is blueshifted while higher-order lines are redshifted suggesting complex gas kinematics; their relative ratios are inconsistent with a single, passive absorbing screen. The line depths require absorption of both the BLR and…

Psalm 58 is about the maga-klan... Here it is (slightly shorted to meet my Mastodon site's posting length limits.)
...
Do you rulers indeed speak justly? Do you judge people with equity?
No, in your heart you devise injustice, and your hands mete out violence on the earth.

Break the teeth in their mouths, O God;
Lord, tear out the fangs of those lions!
Let them vanish like water that flows away; when they draw the bow, let their arrows fall s…

Bible Gateway passage: Psalm 58 - New International Version
Psalm 58 - For the director of music. To the tune of “Do Not Destroy.” Of David. A miktam. Do you rulers indeed speak justly? Do you judge people with equity? No, in your heart you devise injustice, and your hands mete out violence on the earth. Even from birth the wicked go astray; from the womb they are wayward, spreading lies. Their venom is like the venom of a snake, like that of a cobra that has stopped its ears, that will not heed the tune of the charmer, however skillful the enchante…

GRB 250702B: Discovery of a Gamma-Ray Burst from a Black Hole Falling into a Star
Gamma-ray bursts are the most luminous electromagnetic events in the universe. Their prompt gamma-ray emission has typical durations between a fraction of a second and several minutes. A rare subset of these events have durations in excess of a thousand seconds, referred to as ultra-long gamma-ray bursts. Here, we report the discovery of the longest gamma-ray burst ever seen with a ~25,000 s gamma-ray duration, GRB 250702B, and characterize this event using data from four instruments in the Int…

WIde Separation Planets In Time (WISPIT): A Gap-clearing Planet in a Multi-ringed Disk around the Young Solar-type Star WISPIT 2
In the past decades several thousand exoplanet systems have been discovered around evolved, main-sequence stars, revealing a wide diversity in their architectures. To understand how the planet formation process can lead to vastly different outcomes in system architecture we have to study the starting conditions of planet formation within the disks around young stars. In this study we are presenting high resolution direct imaging observations with VLT/SPHERE of the young ($\sim$5 Myr), nearby ($…

Electron coherent phonon coupling in Pr$_{0.5}$Ca$_{1.5}$MnO$_4$ measured with ultrafast broadband spectroscopy
Photoexcitation of single-layered La$_{0.5}$Mn$_{1.5}$MnO$_4$ has played a key role in understanding orbital ordering and non-thermal states in the manganites. However, while orbital ordering in La$_{0.5}$Sr$_{1.5}$MnO$_4$ breaks the in-plane C$_4$ symmetry, many layered manganites show much more complex phase diagrams in which orbital ordering emerges from an already symmetry-broken high-temperature phase and also exhibit additional low-temperature phases. In this work, we examine the role of …

AI Behavioral Science
We discuss the three main areas comprising the new and emerging field of "AI Behavioral Science". This includes not only how AI can enhance research in the behavioral sciences, but also how the behavioral sciences can be used to study and better design AI and to understand how the world will change as AI and humans interact in increasingly layered and complex ways.

AI-Powered Assistant for Long-Term Access to RHIC Knowledge
As the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory concludes 25 years of operation, preserving not only its vast data holdings ($\sim$1 ExaByte) but also the embedded scientific knowledge becomes a critical priority. The RHIC Data and Analysis Preservation Plan (DAPP) introduces an AI-powered assistant system that provides natural language access to documentation, workflows, and software, with the aim of supporting reproducibility, education, and future discovery.

BlackTHUNDER: Shedding light on a dormant and extreme little red dot at z=8.50
Recent photometric surveys with JWST have revealed a significant population of mysterious objects with red colours, compact morphologies, frequent signs of active galactic nucleus (AGN) activity, and negligible X-ray emission. These 'Little Red Dots' (LRDs) have been explored through spectral and photometric studies, but their nature is still under debate. As part of the BlackTHUNDER survey, we have observed UNCOVER_20466, the second most distant LRD known (z=8.5), with the JWST/NIRSpec IFU. Pr…
