#lsst — Public Fediverse posts

Professor Andjelka B. Kovačević’s video presentation for the IAU Symposium 404 is now online - “Multiscale Coherence for Astrobiology and Technosignatures with the Vera C. Rubin Observatory LSST” (Kovačević, Mason, Ciprijanović et al.).

Weekly Update from the Open Journal of Astrophysics – 18/04/2026

It is Saturday morning, and therefore time for yet 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 82 and the total so far published by OJAp up to 530.

I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter (which nobody should be using); these announcements also show the DOI for each paper.

The first paper to report this week is “Beyond Spherical geometry: Unraveling complex features of objects orbiting around stars from its transit light curve using deep learning” by Ushasi Bhowmick & Shivam Kumaran (Indian Space Research Institute, Ahmedabad, India). This study uses deep neural networks to predict the shape of objects orbiting stars based on their transit light curves, demonstrating the potential to extract geometric information from these systems. It was published on Monday 13th April in the folder Earth and Planetary Astrophysics and the overlay can be seen here:

The second paper for this week, also published on Monday 13th April Apil in the folder but in the folder Astrophysics of Galaxies, is “statmorph-lsst: Quantifying and correcting morphological biases in galaxy surveys” by Elizaveta Sazonova (U. Waterloo, Canada) and an international cast of 18 others. This paper presents an investigation of potential biases in quantitative morphology metrics used in galaxy evolution studies, proposing two new measurements to resolve biases, and provides a related Python package (statmorph-lsst), which can be found here on github.

Next one up, the third paper of the week, one of four published on Friday 17th April, is “Disentangling the galactic and intergalactic components in 313 observed Lyman-alpha line profiles between redshift 0 and 5” by Siddhartha Gurung-López (Universitat de València, Spain) and 7 others based in Spain and Germany. Published in the folder Astrophysics of Galaxies, this paper uses the zELDA package to analyze Lyman-alpha photons from star-forming galaxies, revealing IGM effects dominate Lyman-alpha observability at high redshifts, while galactic outflows become more important at lower z.

The fourth paper this week, also published on Friday 17th April is “Using Symbolic Regression to Emulate the Radial Fourier Transform of the Sérsic Profile for Fast, Accurate and Differentiable Galaxy Profile Fitting” by Tim B. Miller (Northwestern University, USA) and Imad Pasha (Yale University, USA). This one is published in the folder Instrumentation and Methods for Astrophysics: it develops an emulator for galaxy profile fitting in Fourier space, improving speed by 2.5 times with minimal accuracy loss, aiding in managing increasing data flow.

The fifth paper for this week is “The THESAN project: Lyman-alpha emitters as probes of ionized bubble sizes” by Meredith Neyer (MIT, USA) and 6 others based in the USA, Colombia, Canada, Japan and UK. The study uses THESAN simulations to explore how Lyman-alpha emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization, providing a framework for interpreting LAE surveys. This was published on Friday 17th April in the folder Astrophysics of Galaxies.

The sixth and final paper for this week is “Closed-Form Statistical Relations Between Projected Separation, Semimajor Axis, Companion Mass, and Host Acceleration” by Timothy D Brandt (Space Telescope Science Institute, USA). This was published on Friday 17th April in the folder Solar and Stellar Astrophysics. In this paper the author derives statistical relationships between radial velocity, a companion’s mass, and projected separation, useful for calculations requiring derivatives. The results are verified with empirical comparisons to existing literature.

Rubin Observatory spustil alertový systém
📡 Historický milník: Observatoř Vera C. Rubin v Chile spustila 24. 2. real-time alertový systém. První noc — 800 000 alertů: supernovy, proměnné hvězdy, aktivní jádra galaxií, asteroidy.
Cíl: až 7 milionů alertů/noc. Změny hlášeny do 2 minut od snímku. Největší digitální kamera (3 200 Mpx) začíná plnit účel. Letos startuje desetiletý průzkum LSST.

#RubinObservatory #LSST #Astronomy #Astronomie #Supernova #OpenScience #DataScience

#LSST performs very well for large impactors ☄️, discovering about 79.7% of objects larger than 140 m before impact. Only 50.3% of 50–140 m impactors, 26.8% of 20–50 m impactors, and 10.5% of 10–20 m impactors are discovered 🔭 at all. About 60% of large impactors fail to reach a one-year warning threshold. Upper mid-size objects are usually discovered only a few months before impact 💥 https://www.newplanetarium.com/journal/2026-01-29

#RubinObservatory #AsteroidThreat

"Rubin Observatory sends out thousands of data alerts" by GeekWire / @alanboyle - The first night of astronomical alerts from the high-resolution sky survey of #RubinObservatory #LSST was a batch of 800,000 possible new object detections. This is apparently the new normal. Astronomers have a flood of new data to process every day. https://www.geekwire.com/2026/rubin-observatory-data-alert/ #space #astronomy #tech

Rubin Observatory spots an #asteroid that spins fast enough to set a record
The asteroid, known as #2025MN45, is nearly half a mile (710 meters) in diameter and makes a full rotation every 1.88 minutes, based on an analysis of data from the #VeraCRubinObservatory in #Chile.
2025 MN45 is one of more than 2,100 solar system objects detected during the observatory’s commissioning phase. Over time, the #LSST Camera tracked variations in the light reflected by those objects.

Rubin Observatory and the Galaxies

Starting in late 2025, when it begins the decade-long Legacy Survey of Space and Time (LSST), Rubin will capture skies like these in more detail than ever before.

"Software suggests Rubin Observatory will discover millions of solar system objects" by GeekWire / @alanboyle - Getting a grasp on what effect the high-resolution sky survey of #RubinObservatory #LSST will have: using previous rates of discovery of asteroids to estimate what we don't yet know, multi-university Sorcha simulation forecasts LSST may discover half of all then-known asteroids within a year. And its majority share will continue to grow. https://www.geekwire.com/2025/sorcha-software-rubin-observatory-millions/ #space #astronomy

Software predicts a bonanza of solar system discoveries
A new type of computer simulation predicts that the Vera C. Rubin Observatory in Chile will discover millions of previously undetected objects in the solar system over the course of the coming decade.

The discovery campaign, which is due to begin in earnest later this year, should expand th

The @VRubinObs 220-ton mount takes 5 seconds ⏱️ to move to its next position.
Rubin will do near-real-time processing of new images every night and release world-public alerts within 60 seconds for objects that have moved ☄️ or changed. Every night, Rubin Observatory will produce 20 terabytes of data 💽 https://rubinobservatory.org/explore/how-rubin-works/technology

Astronomers process test images at Rubin Observatory
The Vera C. Rubin Observatory in Chile has begun generating test images of the night sky, thanks to the Simonyi Survey Telescope and its giant camera as well as a data management team that includes scientists from the University of Washington.

Team members started taking on-sky engineering data w

Up Close With the Completed 3.2-Gigapixel #LSST #Camera

Engineers at the #SLAC National Accelerator Laboratory have completed work on the Legacy Survey of #Space and Time camera. The device is the world's largest digital camera and will be the centerpiece of a 10-year mission to map the night sky from the Vera C. Rubin #Observatory in #Chile.

Hello #Astrodon ! I still feel #NewHere so here’s an #introduction . I’m an #extragalactic astronomer at the #OpenUniversity in the UK, interested in submm blobs, strong gravitational lensing, #MachineLearning applications, crowdsourced data mining (#CitizenScience), and #OpenScience. I do fun stuff in the European Open Science Cloud #EOSC and work with #Euclid, #LSST #DESC #SLSC, #Herschel, #ALMA, #HST, #JWST and pretty much anything that’ll give me observational data tbh
