ALMA, as part of the Event Horizon Telescope, is unveiling a new image of our Milky Way's supermassive black hole, Sagittarius A*, in which strong magnetic fields can be seen…
The most exciting part is that this hints to a jet that would be hidden from our vantage point in our galaxy… but imagine that! We might be like M87, just at a smaller scale!

Astronomers unveil strong magnetic fields spiraling at the edge of Milky Way’s central black hole | ALMA
A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarised light for the first time, this new view of the monster lurking at the heart of the Milky Way galaxy has revealed...

Energy Recovery System for Large Telescopes
In this paper, a kinetic energy recovery system for large telescopes is presented, with the Atacama Large Aperture Submm Telescope (AtLAST) as a possible target application. The system consists of supercapacitors integrated in the DC-link of motor inverters through a bidirectional DC-DC converter. The optimal system design, based on the energy flow analysis within the telescope's power electronics, is introduced. The proposed system is simulated as part of the telescope's drives, providing not …

In 2012 the US spy office NRO had 2 old obsolete spy satellites collecting dust that they decided to give away to NASA. US spies have more $$$ in spare parts than NASA has for space exploration.

A study of 10 Rotating Radio Transients using Parkes radio telescope
Rotating Radio Transients (RRATs) are a relatively new subclass of pulsars that emit detectable radio bursts sporadically. We conducted an analysis of 10 RRATs observed using the Parkes telescope, with 8 of these observed via the Ultra-Wideband Receiver. We measured the burst rate and produced integrated profiles spanning multiple frequency bands for 3 RRATs. We also conducted a spectral analysis on both integrated pulses and individual pulses of 3 RRATs. All of their integrated pulses follow a…

FORECASTOR -- II. Simulating Galaxy Surveys with the Cosmological Advanced Survey Telescope for Optical and UV Research
The Cosmological Advanced Survey Telescope for Optical and UV Research (CASTOR) is a planned flagship space telescope, covering the blue-optical and UV part of the spectrum. Here we introduce the CASTOR image simulator, a Python GalSim package-based script capable of generating mock CASTOR images from an input catalogue. We generate example images from the CASTOR Wide, Deep, and Ultra-Deep surveys using simulated light-cones from the Santa Cruz Semi-Analytic Model. We make predictions for the p…

Jodrell Bank's 'Lovell' telescope (photo again from probably 80 or 81); it's not far outside #Manchester and has been doing Radio astronomy since the 50's

Det gjŸres mye rart i offentlige ansettelser i #Norge òg, men at en #landshövding (tilsvarende statsforvalter/fylkesmann) kunne ha sluppet unna med å ansette en kompis til topplederstilling ved bare å henge opp utlysning i resepsjonen er svært merkelig.

Correction method applied to MC simulated LST images affected by clouds
We present the results of a preliminary study of a correction method applied to the Imaging Atmospheric Cherenkov Telescope images affected by clouds. The studied data are Monte Carlo simulations made with CORSIKA, imitating the very high energy events registered by the Large-Sized Telescopes, a type of telescope within the future Cherenkov Telescope Array. We implement the cloud correction method in the ctapipe/lstchain analysis framework. The correction is based on a simple geometrical model …
