#verylargearray — Public Fediverse posts

A recent upgrade to a commercial cell phone tower near the U.S. National Science Foundation #VeryLargeArray (NSF VLA) briefly disrupted some observations, but operations are back to normal following a cooperative effort between the NSF National Radio Astronomy Observatory (NSF NRAO) and the wireless provider: https://public.nrao.edu/news/quiet-sky/

Weekly Update from the Open Journal of Astrophysics – 23/05/2026

It’s Saturday once again, so time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further six papers, bringing the number in Volume 9 (2026) to 110 and the total so far published by OJAp up to 558.

I will continue to include the posts made on our Mastodon account (on Fediscience); these announcements also show the DOI for each paper.

The first paper to report this week, published on Monday 18th May in the folder Instrumentation and Methods for Astrophysics is “Edges In Coadded Images” by Erin Sheldon (Brookhaven National Laboratory, USA). This paper describes a study exploring how image discontinuities and noise impact weak gravitational lensing measurements, finding no significant biases under typical conditions. Biases occur only in extreme cases, but can be mitigated.

The second paper for this week, also published on Monday 18th May but in the folder Cosmology and Nongalactic Astrophysics, is “Joint cosmological fits to DESI-DR1 full-shape clustering and weak gravitational lensing in configuration space” by A. Semenaite (Swinburne Institute of Technology, Australia) and 72 other authors from all round the world. This paper presents a cosmological analysis of correlations between the DESI-DR1 Bright Galaxy Survey and Luminous Red Galaxy samples and overlapping shear measurements from various weak lensing surveys.

Next one up, the third paper of the week, and the third published on Monday 18th May, and in the folder Cosmology and Nongalactic Astrophysics is “Probing Dark Energy Microphysics with kSZ Tomography” by Julius Adolff, Selim Hotinli and Neal Dalal (all of the Perimeter Institute, Canada). This paper explores how kinetic Sunyaev-Zel’dovich tomography and galaxy clustering can enhance our understanding of dark energy and its effects, potentially revealing its microphysical properties in future surveys.

The fourth paper this week, published on Wednesday May 20th is “A Census of Variable Radio Sources at 3 GHz” by Yjan A. Gordon, Peter S. Ferguson, Michael N. Martinez and Eric J. Hooper (all of the University of Wisconsin, USA). This article, published in the folder Astrophysics of Galaxies, uses data from the Very Large Array Sky Survey to analyze variability in the radio sky, finding most changes consistent with blazars and quasars.

The fifth article of this week was published on Friday 22nd May in the folder Instrumentation and Methods for Astrophysics. The title is “Uncovering the Next Galactic Supernova with the Vera C. Rubin Observatory” by John Banovetz (Lawrence Berkeley Lab., USA), Claire-Alice Hebert & Peter B. Denton (Brookhaven National Lab., USA), Dan Scolnic (Duke University, USA), Anze Slosar (Brookhaven) and Chris Walter (Duke). The paper presents a study simulating how effectively the Vera C. Rubin Observatory can localize supernovae using neutrino triggers, finding a 57-97% success rate based on stellar mass density predictions.

Last, but by no means least, this week we have “Pulsar timing solutions for 17 pulsars at 150 MHz from the Irish LOFAR station” by David J. McKenna (ASTRON, The Netherlands), Evan F. Keane (Trinity College Dublin, Ireland), Peter T. Gallagher (DIAS, Ireland) and Joe McCauley (Trinity). This was published on Friday 22nd May in the folder High-Energy Astrophysical Phenomena. It presents a demonstration of the use of international Low Frequency Array (LOFAR) stations in tracking and characterizing pulsars, providing new insights into these neutron stars’ emission properties.

A study based on @thenrao VLA archival data finds that Operational Data Sharing with #SpaceX has reduced L-band system temperature, and support for "earlier coordinated studies and demonstrate[s] that while StarLink’s DtC transmissions can produce measurable effects, mitigation frameworks like ODS provide effective protection to scientific data quality."

The #VeryLargeArray is, in case you were not aware, very large indeed! Temperature is a toasty 96°F and going higher today. This is where they filmed parts of #Contact and #2010 films.

Did you know #SpaceX had to cut a deal with the #VLA’s Nat’l Radio Astronomy Observatory org to turn off all bandwidth from space as the satellites pass overhead and they pass over CONSTANTLY and they are NUMEROUS and ALL OVER THE SKY and visible at night w/naked eye.

What a day! Very tired!

Today was spent more sightseeing in and around #ABQ.

Starting off with a trip to #OldTown and the #Albuquerque #Museum which we were there for like 2.5 hours. What an amazing collection!

Then we spent another 2 hours or so and strolled around #OldTown.

Next we went to get a bite to eat and some adult beverages and we capped off the day visiting #SandiaPeak and the #Tramway up to the top of the #Sandia #Mountains!

Some beautiful views and great company.

Tomorrow is another long day.

Tomorrow morning we're heading south to #Socorro and west to #Magdalena to see the #VLA (#VeryLargeArray).

Yesterday was spent in #Taos and #SantaFe and tomorrow is going to be spent in

A decade ago this week, I learned that they open the Trinity test site to the public twice a year and I was underemployed so convinced @mct to go on a roadtrip why not. The Trinity site was interesting but the real treat was stopping at the VLA the day before. I was just starting to dabble in signal processing and one of the tour guides was working on their FPGAs—I learned a lot. Also the weather was incredible. #verylargearray #newmexico https://www.flickr.com/search/?user_id=80321933%40N00&sort=date-taken-desc&text=&view_all=1&min_taken_date=1396335600&max_taken_date=1397631599

Very Large Array (VLA)

The VLA is a system consisting of 27 radio telescopes, each with a diameter of 25 meters. It is installed on a Y-shaped rail system, each 21 km long, on which it can be positioned in various configurations.

The photo shows a prairie landscape with eight telescopes in a row up to the horizon. A snowstorm is approaching and darkening the sky.

"I have a VLA."

"What? A Very Large Array? I find this highly doubtful. Where? I want to see this VLA of yours."

"I don't know what you're talking about. You see it all the time."

"What? Well, what are you talking about?"

"My Very Large Ass."

A Sneak Peek at the Next Generation Very Large Array's New Antennae

The NRAO is planning a dramatic new upgrade to the Very Large Array, creating a network of telescopes that spans a large part of North America. As part of this upgrade, they got a sneak peek at the prototype radio antenna built in Germany. The 18-meter dish has 76 individual panels arranged in an 8-sided shape. The final array will eventually consist of 244 dishes in the US, Mexico, and Canada.
