Towards a sub-kelvin cryogenic Fabry-Perot silicon cavity
We report on the development of a sub-kelvin, single-crystal silicon Fabry-Perot cavity. Operating such a cavity below 1~K should reduce the thermal noise limit of the cavity, and by this way address the current limitations of ultrastable lasers. To further decrease mechanical losses, mirrors with silicon substrates and crystalline coatings are optically contacted to the spacer, resulting in a room-temperature finesse of 220,000. To operate our cavity at sub-kelvin temperatures, we use a diluti…

A broad linewidth, compact, millimeter-bright molecular emission line source near the Galactic Center
A compact source, G0.02467-0.0727, was detected in ALMA \threemm observations in continuum and very broad line emission. The continuum emission has a spectral index $α\approx3.3$, suggesting that the emission is from dust. The line emission is detected in several transitions of CS, SO, and SO$_2$ and exhibits a line width FWHM $\approx160$ \kms. The line profile appears Gaussian. The emission is weakly spatially resolved, coming from an area on the sky $\lesssim1"$ in diameter ($\lesssim10^4$ …

Dallas Cowboys Could Make Trade For Pro Bowl Running Back https://www.yardbarker.com/nfl/articles/dallas_cowboys_could_make_trade_for_pro_bowl_running_back/s1_17150_40401965

Dallas Cowboys Could Make Trade For Pro Bowl Running Back
The Dallas Cowboys have not exactly handled their backfield situation well this offseason. The Cowboys allowed running back Tony Pollard to walk in free agency, but didn’t immediately sign anyone to replace him. Many felt they would pursue Derrick Henry, but they watched as he took his talents to the Baltimore Ravens. At that point, the general consensus was that Dallas would select a halfback in the NFL Draft, and many had pegged Texas standout Jonathon Brooks as someone the Cowboys would ta…

Sulfur Dioxide and Other Molecular Species in the Atmosphere of the Sub-Neptune GJ 3470 b
We report observations of the atmospheric transmission spectrum of the sub-Neptune exoplanet GJ 3470 b taken using the Near-Infrared Camera (NIRCam) on JWST. Combined with two archival HST/WFC3 transit observations and fifteen archival Spitzer transit observations, we detect water, methane, sulfur dioxide, and carbon dioxide in the atmosphere of GJ 3470 b, each with a significance of >3-sigma. GJ 3470 b is the lowest mass -- and coldest -- exoplanet known to show a substantial sulfur dioxide fe…

just surfaced via bittorrent, from 50 years ago last month: a truly atrocious audience tape of the very last gig by the classic modern lovers feat. ernie brooks & jerry harrison, at the winter ball in #boston. by my count, 9 originals/covers not on any other tapes (besides richman solo demos). "johnny too bad"! the ad makes it seem like they were gonna play with moe tucker (& georg…

1. The speed with which the climate is now changing is faster than (almost) all scientists thought possible.
2. There is now zero prospect of holding the average temperature increase this century to below 1.5°C; even 2°C is beginning to slip out of reach. The vast majority of climate scientists know this, but rarely if ever give voice to this critically important reality.
3. At the same time, the vast majority of people still haven’t a clue about what’s going on – and what this means for them and everything they hold dear.
4. The current backlash against existing (already wholly inadequate) climate measures is also accelerating – and will cause considerable political damage in 2024. Those driving this backlash represent the same old climate denial that has been so damaging over so many years.
5. The science-based institutions on which we depend to address this crisis have comprehensively failed us. The Intergovernmental Panel on Climate Change is incapable of telling the whole truth about accelerating climate change; the Conference of the Parties (under the UN Framework Convention on Climate Change) has been co-opted by the fossil fuel lobby to the point of total corruption.
6. By not calling out these incontrovertible realities, mainstream scientists are at risk of becoming the new climate deniers."
