And if there is no personal connection between recommendation letter writer and the applicant, the letter has higher weight - letters from friends are downgraded. It'sthe EB green card track. I'd check if these ppl are legitimate scientists and doing good quality science before ignoring them 2/2

Yes, I can confirm that this is legit requirement for application for permanent residency; I went through it myself a couple of years ago (on a green card now). The reason for it is, that if an applicant is a world renowned and respected scientist then others in the field would know about them 1/2

NEW: NRAO to Outfit the VLBA with New Ultra Wideband Receivers

A major upgrade is coming to the NSF Very Long Baseline Array (NSF VLBA) – state-of-the-art ultra wideband receivers capable of operating across the frequency range of 8 - 40 gigahertz (GHz).

This brings me to my childhood, and all the awe and excitement watching and learning about the celestial phenomena. I'm still remembering the feeling of pure fascination. Good to get reminded why we do what we do even though a lot of my work is administration, teaching or management nowadays 😌

Oh my god!! Too funny!! 😂😂😂

And sadly many more are just being let go, perhapsnow more than ever in the last decade. Sometimes the senior ones take it upon themselves claiming (very) early retirement to give a fighting chance to junior colleagues. But really, how bad can it get? I worry too 😟

And a full press release on these observations is here, from 20 yrs ago:

This is a classic. And such a fascinating one!! Here is a movie based on real radio waves emitted from the system's relativistic jets of matter and energy launched from the vicinity of the central compact object (likely stellar black hole) over a period of 1.5 months:

Trees are a lifeline, but I agree that it should go hand in hand with technological advances to support each other.. wishful thinking? 2/2

I now live in New Mexico, where tall trees are scarce unless one is near a river or at 9000ft or higher, and I have never fought for trees more than now. Shade is almost a luxury here... Funny how things can get into the right perspective unexpectedly. 1/2

Caption for Figure 1: Overview of EMUSE (Evolutionary Map of the Universe Search Engine). Starting with the open-source OpenCLIP model, which is pre-trained on approximately 2.3 billion image-text pairs from the LAION dataset, we further fine-tuned it using an image-text dataset of extended radio sources in the EMU-PS1 survey. The fine-tuned model is then used to generate image embeddings of EMU sources based on PNG images from the EMU and AllWISE surveys at the positions of extended radio sources identified in the RG-CAT catalogue. The fine-tuned model, along with the generated image embeddings and catalogue metadata is integrated into the EMUSE application framework to retrieve similar sources. EMUSE facilitates the search of the embedding database and outputs a table of EMU survey radio sources that are similar to a given image or text prompt. The search engine is accessible at https://askap-emuse.streamlit.app/

Things are progressively getting out of hand... on too many fronts, though this one is astronomy and perhaps ultimatelyimpeding sci fi predictions (just wait for it) focused. Sigh..

Here is SS 433, the first identified microquasar.

It is about one of the most exotic star systems known, a binary star microquasar consisting of a stellar-mass black hole and its companion, a giant star.

ORC candidates with unconfirmed host galaxies. The corresponding optical images are sourced from the DECaPS2 survey due to the absence of DESI LS DR10 coverage. In the top panel, white arrows indicate one central galaxy and two additional galaxies at the locations of radio emission peaks, making it challenging to conclusively identify the origin of the circular emission with the current data. In the bottom panel, the high density of sources in the optical image complicates the confirmation of a host galaxy. Full caption in the paper.

Go EMU!! Go ! 🙃

Left: Background-subtracted and exposure-corrected NuSTAR mosaic image of the galaxy cluster Abell 3667 in the 4–24 keV energy band, combining data from both telescopes. The image was smoothed using a Gaussian kernel with a σ = 17.2 arcsec (7 pixels) to match NuSTAR’s PSF of ∼ 18 arcsec FWHM. The solid green circle (4.5 arcmin radius) indicates the region from which the source spectra were extracted, while the dashed green circles mark the regions used to extract the background spectra. The overlapping areas are excluded from the background regions. Right: Mosaicked Chandra image of Abell 3667, showing the locations of the point sources. The cyan box outlines the extent of our NuSTAR observations.

Dark Emu in full flight, winter solstice night. The dark Coal Sack nebula under the Southern Cross forms the emu's head. The glowing area at the emu's feet (near the tree) marks the centre of the Milky Way galaxy. A beautiful treasure in our sky. June 21st 2025 #astrophotography

MUSE view of the Sculptor Galaxy, detail.

This image shows a detailed, thousand-color image of the Sculptor Galaxy captured with the MUSE instrument at ESO’s Very Large Telescope (VLT). Regions of pink light are spread throughout this whole galactic snapshot, which come from ionised hydrogen in star-forming regions. These areas have been overlaid on a map of already formed stars in Sculptor to create the mix of pinks and blues seen here.

This image shows the Sculptor Galaxy in a new light. This false-color composition shows specific wavelengths of light released by hydrogen, nitrogen, sulphur, and oxygen. These elements exist in gas form all over the galaxy, but the mechanisms causing this gas to glow can vary throughout the galaxy. The pink light represents gas excited by the radiation of newborn stars, while the cone of whiter light at the center is caused by an outflow of gas from the black hole at the galaxy’s core.

Astronomers used ESO’s Very Large Telescope and MUSE instrument to create a thousand-color view of the Sculptor Galaxy (NGC 253), revealing its stars, gas, and dust in incredible detail. This 50-hour observation helps decode the galaxy’s complex internal structure.

Holy crap!! Isn't going with DNR without permission from the patients themselves an actual murder...???

Hmm, I am already self proclaimed bee 🐝 guardian; shall I become "semicolon protector" too? 😁

Speaking of the #ngVLA, we've announced several new partnerships and collaborations lately! See thread below ⬇️
