The effects of the spin and quadrupole moment of SgrA* on the orbits of S stars
Measuring the astrometric and spectroscopic data of stars orbiting the central black hole in our galaxy (Sgr A*) offers a promising way to measure relativistic effects. In principle, the "no-hair" theorem can be tested at the Galactic Center by monitoring the orbital precession of S-stars due to the angular momentum (spin) and quadrupole moment of Sgr A*. Closer-in stars, more strongly affected by the black hole's rotation, may be required. GRAVITY+ could detect such stars that are currently to…

"Needless to say, putting American data in the hands of a company whose CEO boasts about his company’s capacity to kill and intimidate doesn’t inspire confidence that the data will be handled responsibly."

Trump appears to be building an unprecedented spy machine that could track Americans
As Donald Trump and his administration pursue crippling austerity measures across the country, they’re plunging millions into a company that’s expanding the government’s ability to spy on its own citizens.

Exploring the keV-scale physics potential of CUORE
We present the analysis techniques developed to explore the keV-scale energy region of the CUORE experiment, based on more than 2 tonne yr of data collected over 5 years. By prioritizing a stricter selection over a larger exposure, we are able to optimize data selection for thresholds at 10 keV and 3 keV with 691 kg yr and 11 kg yr of data, respectively. We study how the performance varies among the 988-detector array with different detector characteristics and data taking conditions. We achiev…

The Sunspot Solar Observatory Data Archive: Continuing Operations at the Dunn Solar Telescope
The Sunspot Solar Observatory Data Archive (SSODA) stores data acquired with the suite of instruments at the Richard B. Dunn Solar Telescope (DST) from February 2018 to the present. The instrumentation at the DST continues to provide high cadence imaging, spectroscopy, and polarimetry of the solar photosphere and chromosphere across a wavelength range from 3500Å to 11,000Å. At time of writing, the archive contains approximately 374 TiB of data across more than 520 observing days (starting on …

Vet att samhället styrs idag absolut inte som ett företag. Inget större bolag skulle rymma den inkompetensen att styrelsen säger "vi har stora investeringsmöjligheter med säkra framtida anläggningar men vi kommer inte låna till dem för vi måste "spara i ladorna"" och överleva på marknaden. Men så görs idag med t ex utbildning, infrastruktur, klimatomställning och migration. Och kapitalet, som vet bättre, driver igenom det för att de inte vill samhällets bästa utan sitt

Cephalopods, vision’s next frontier
For decades, scientists have been teased by the strange but inaccessible cephalopod visual system. Now, thanks to a technological breakthrough from a lab in Oregon, data are finally coming straight from the octopus brain.

PyTICS: An Iterative Method for Photometric Lightcurve Intercalibration using Comparison Stars
Intensive reverberation mapping monitoring programs combine ground-based photometric observations from different telescopes, requiring intercalibration of lightcurves to reduce systematic instrumental differences. We present a new iterative algorithm to calibrate photometric time-series data of active galactic nuclei (AGN) using 100s of comparison stars on the same images, building upon the established method of ensemble photometry. The algorithm determines telescope-specific and epoch-specific…

Study of $D_{s1}(2460)^{+}\to D_{s}^{+}π^{+}π^{-}$ in $B\to {\bar{D}}^{(*)}D_{s}^{+}π^{+}π^{-}$ decays
An amplitude analysis of the $D_{s1}(2460)^+\to D_{s}^{+}π^{+}π^{-}$ transition is performed simultaneously in $B^{0}\to D^{-}D_{s}^{+}π^{+}π^{-}$, $B^{+}\to{\bar{D}}^{0} D_{s}^{+}π^{+}π^{-}$, and $B^{0}\to D^{*-}D_{s}^{+}π^{+}π^{-}$ decays. The study is based on a data sample of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of $\sqrt{s}=7,8,$ and $13\,$TeV, corresponding to a total integrated luminosity of $9\,\rm{fb}^{-1}$. A clear double-peak str…

Euclid: Early Release Observations of ram-pressure stripping in the Perseus cluster. Detection of parsec scale star formation with in the low surface brightness stripped tails of UGC 2665 and MCG +07-07-070
Euclid is delivering optical and near-infrared imaging data over 14,000 deg$^2$ on the sky at spatial resolution and surface brightness levels that can be used to understand the morphological transformation of galaxies within groups and clusters. Using the Early Release Observations (ERO) of the Perseus cluster, we demonstrate the capability offered by Euclid in studying the nature of perturbations for galaxies in clusters. Filamentary structures are observed along the discs of two spiral galax…
