The Cryogenic Lagrangian Exploration Module: a rotating cryostat for the study of quantum vortices in Helium II via particle seeding
The study of quantum vortex dynamics in HeII offers great potential for advancing quantum-fluid models. Bose-Einstein condensates, neutron stars, and even superconductors exhibit quantum vortices, whose interactions are crucial for dissipation in these systems. These vortices have quantized velocity circulation around their cores, which, in HeII, are of atomic size. They have been observed indirectly, through methods such as second sound attenuation or electron bubble imprints on photosensitive…

Petition of Right, (1628)
was a petition sent by the English Parliament to King Charles I,
complaining of a series of breaches of law.
The petition sought recognition of four principles:
🔸no taxation without the consent of Parliament,
🔸no imprisonment without cause,
🔸no quartering of soldiers on subjects,
🔸and no martial law in peacetime.
After dismissing his second Parliament,
Charles imposed a "forced loan", an effective tax wh…

The Type II SN 2025pht in NGC 1637: A Red Supergiant with Carbon-rich Circumstellar Dust as the First JWST Detection of a Supernova Progenitor Star
We present follow-up imaging and spectroscopy and pre-explosion imaging of supernova (SN) 2025pht located in NGC 1637 at 12 Mpc. Our spectroscopy shows that SN 2025pht is a Type II SN with broad lines of hydrogen and with minimal line-of-sight extinction inferred from Na I D absorption. NGC 1637 was the target of several epochs of Hubble Space Telescope (HST) and James Webb Space Telescope (JWST) imaging covering the site of SN 2025pht from 31 to 0.7 yr prior to discovery. Using a follow-up HST…

Direct Imaging Explorations for Companions from the Subaru/IRD Strategic Program II; Discovery of a Brown-dwarf Companion around a Nearby mid-M~dwarf LSPM~J1446+4633
We report the discovery of a new directly-imaged brown dwarf companion with Keck/NIRC2+pyWFS around a nearby mid-type M~dwarf LSPM~J1446+4633 (hereafter J1446). The $L'$-band contrast ($4.5\times10^{-3}$) is consistent with a $\sim20-60\ M_{\rm Jup}$ object at 1--10~Gyr and our two-epoch NIRC2 data suggest a $\sim30\%$ ($\sim3.1σ)$ variability in its $L'$-band flux. We incorporated Gaia DR3 non-single-star catalog into the orbital fitting by combining the Subaru/IRD RV monitoring results, NIRC…

As I read the daily news I am reminded of history.
In particular the history of Charles I, Louis XVI, Nicholas II, Maximilian I (of Mexico).
I remember history, 'cause, as is said, if I forget it I would be doomed to repeat it.

Nearly Full-Sky Low-Multipole CMB Temperature Anisotropy: II. Angular Power Spectra and Likelihood
We present a CMB temperature power spectrum measurement at large angular scales from WMAP and Planck maps that were cleaned of foregrounds using a template-based approach described in a companion paper. We recover essentially the full-sky CMB information at multipoles $\ell<30$ with only 1% of pixels near the Galactic plane masked and no inpainting. Notable features continue to appear: (a) a low quadrupole power compared to the best-fit Planck 2018 $Λ$CDM spectrum at $2.2σ$, (b) a dip in the …

Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of $α$ Cen A. II. Binary Star Modeling, Planet and Exozodi Search, and Sensitivity Analysis
JWST observed our closest solar twin, $α$ Cen A, with the MIRI coronagraph in F1550C (15.5 $μ$m) at three distinct epochs between August 2024 and April 2025. For the first time with JWST, we demonstrate the application of reference star differential imaging to simultaneously subtract the coronagraphic image of a primary star and the point spread function (PSF) of its binary companion to conduct a deep search for exoplanets and dust emission. We achieve a typical 5$σ$ point source contrast se…
