Final SPTpol TE, EE power spectrum from full 4-year data set! "dataset is well-fit by the ΛCDM model, for which we find H0=70.48±2.16 km/s/Mpc and Ωm=0.271±0.026 using only the SPTpol data" Great PhD thesis work from Jody Chou! #southpole

In this new paper led by Joshiwa van Marrewijk we demonstrated that AtLAST’s 50m-diameter provides the highest levels of correlation of atmospheric signals across adjacent detectors compared to smaller apertures: AtLAST will be great at removing submm atmospheric signal on large scales 🔭

This optical composite image of the spiral galaxy M83, which is seen nearly face-on, is described in detail on the APOD page: https://apod.nasa.gov/apod/ap190629.html * Star forming regions in pink shine bright within the dusty stellar spiral arms while the central bulge reveals a concentration of old stars.

Keen to see the host galaxy of the MIGHTEE ORC ? Here it is, a massive elliptical that has grown so big by accretion and mergers. - Just published in @rasjournals.bsky.social ui.adsabs.harvard.edu/abs/2025MNRA...

M101 - such a beautiful spiral galaxy. Here a beautiful multi-wavelength collage created by my friend Angel Lopez-Sanchez. Note the huge extent of the HI 21-cm emission. #radioastronomy #galaxies #hydrogen

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the wavelength observation range and scale are shown at the top left of each image.

The EHTC studied the spectacular flare observed during its second campaign on M87, involving over 25 ground-based and space-based telescopes. The authors report the first observation in over a decade of a high-energy gamma-ray flare.

Screenshot of the arXiv summary for the paper arXiv:2313.06392 by M. Lepore et al., showing the arXiv red banner on the top, the paper title ("Feeding and feedback processes in the Spiderweb proto-intracluster"), and the list of authors.

Being cool, the Spiderweb way 🕸️

Marika Lepore led a re-analysis of the central region of the Spiderweb protocluster at z=2.16, combining Chandra X-ray and ALMA SZ data. And we find evidence for a strongly cooling core.

4. I am leaving twitter and looking for an alternative. This seems the best option. Optimistic about the direction of the development.

First post here. Looking forward to blue skies and low precipitable water vapour.
