First light with XRISM 💡 🛰️ ! The X-ray telescope launched in September and has an imager developed by JAXA (Xtend) & spectrometer developed by NASA (Resolve). An observation from both is shown in the press release!
There is one blip: the protective beryllium dewar aperture door on Resolve should be removed, but it's currently stuck. High energy X-rays can pass through this, but lower energies are absorbed. The team will shift conditions a bit and try again.
Is this kind aperture door a new technology though? I think Hitomi had something very similar (but no luck there), yet various previous soft X-ray telescopes had/have some kind of aperture doors.
What makes the door on #XRISM new and untested technology? Serious question, maybe someone knows.
I realize the components are not all off-the-shelf, but not every single piece is reinvented every time. Even the platform can be re-used, like between #XMM-Newton and #INTEGRAL.
Aperture doors exist in many X-ray satellites: #XMM-Newton, #Chandra. I suppose they are somehow different?
There is a whole systems engineering work to reduce the chance of issues like this.
That is to say, of course this is all hard, and it is just sad that 4th attempt to operate an X-ray microcalorimeter telescope is not quite successful, so far.
A random thought while #coding and using #CoPilot#GPT#LLM#AI more and more: sometimes I write a piece of code myself not because it's faster to do so, but because I enjoy it and I think my solution is more interesting.
Does #AI enjoy creative coding as much as I do? If not, it's taking part of my job and not even having fun with it?
Last year, we set the target to fill up our gas storage by 90% by 1 November. We exceeded it by filling up the storage to almost full capacity.
Storage provides an additional reserve in case of strong demand or supply disruptions.
We are strengthening our energy independence with #REPowerEU by saving energy, diversifying our energy supplies, and speeding up the clean energy transition.
@diogoeichert where is your problem @andia ? android? browser?
I have it on firefox. Annoyingly it only started a couple of months ago, before it was good.
Astronomy in Galaxy - #usegalaxy is that. The data analysis platform. 🥳 Thanks to @volodymyr for presenting the work of his team at the European Galaxy Days.
Ok, but I have a sense that astronomers and particle physicists would #usegalaxy in a slightly different way than it is mostly used now. We are just too used to speak to the machines in text, and not in visual UI. So #jupyter in galaxy is one way which will work. Various #API uses could be useful too.
Then, there are cases when Web GUI is the preferred one as long as the inputs and outputs are not locked in in GUI. There is where we put our efforts too.
🌐 Did you know that Europe is home to 3 of the world's top 5 supercomputers?
And guess what? They're about to become accessible to AI start-ups!
Their use already brings new opportunities to:
🔸 improve quality of life of Europeans,
🔸 advance science,
🔸 boost industrial competitiveness,
🔸 ensure Europe’s technological autonomy, and
🔸 help SMEs develop.
Thanks to our investment in the last years, Europe has now become a leader in supercomputing!
@isazi right, thanks, I am just curious who currently uses them.
E.g. I work with #CSCS in #Lugano and major notable customers are #meteosuisse , #WLCG (#particlephysics). I specifically work for #CTA and #SKA astronomical observatories, but their use is not yet substantial.
There any many others too, I am not totally sure about relative use. E.g. #climate modelling is of course a very interesting case
It's just fascinating to be to see what these huge #HPC machines can do.
#EuroHPC is a major development I would say getting comparable with international energy, transport systems. It has major implications for sustainability and even sovereignty. It's great that it was recognized and pursued.
But still, people do not know enough about what it does. Even I, working with institutional #HPC for decades, knew little about national and international scale providers.
@0x3mi@polezaivsani I am not so much criticizing, I am interested in your opinion, I am just pointing out that due to your lack of broad connections with ukrainian people you seem to be a bit out of touch with their views, on their motivation for the war and connection to the state. Don't you think this is possible?
Also, I hope you realize how much harm this causes to Ukrainians. We want it to be over fast. But our long story of life with Russia tells us that stopping now is not the way.
@polezaivsani@0x3mi I actually find that a surprisingly large number of Russians really support the war, even if not too enthusiastically. Then there are others, usually young, who are strongly against the war but usually cannot find a way to resist. Some find a way though, and fight on the Ukrainian side.
But I agree that a common sentiment is that of disillusion and apathy, maybe passively blaming all sides. Probably a consequence of застой generation, and then disillusionment of the 90's.
@davidroessli it is quite a recent feature, since a couple of months I think :)
When they started to replace mechanical displays, the result was actually worse I think. Since before information was shown at once, digital ones change.
