Absence of Radio Emission Reveals an Exceptionally Weak Explosion of the Putative Historical Supernova Pa 30
We present the first deep radio continuum observations of Pa 30, a nebula hosting a unique optical source driven by an ultrafast outflow with a velocity of 16,000 km s$^{-1}$. The nebula was proposed to be the remnant of a white dwarf merger that occurred in 1181CE. We report no detection of the radio diffuse emission from Pa 30 or radio emission from the central source, setting $3σ$ upper limit flux densities of $0.84\,\rm mJy$ and $0.29\,\rm mJy$ at 1.5 GHz and 6 GHz, respectively, for Pa 30…

I used to live in a house by the freeway. When I went anywhere, I had
to be going 65 MPH by the end of my driveway.
I replaced the headlights in my car with strobe lights. Now it looks
like I'm the only one moving.
I was pulled over for speeding today. The officer said, "Don't you know
the speed limit is 55 miles an hour?" And I said, "Yes, but I wasn't going
to be out that long."
I put a new engine in my car, but didn…

Russland meldet weitere Vorstöße in der Ukraine
Die russische Armee schreitet nach Angaben aus Moskau in der Ukraine weiter voran. Zuletzt seien die Dörfer Pawliwka in der südostukrainischen Region Saporischschja und Iwaniwka in der benachbarten Region Dnipropetrowsk eingenommen worden, teilte das Verteidigungsministerium mit. Zudem seien ukrainische Energieanlagen attackiert worden. Das sei eine Reaktion auf ukrainische Angr…

Flare energetics, CME launch and heliospheric propagation for the May 2024 events, as derived from ensemble MHD modelling
Many questions must be answered before understanding the relationship between the emerging magnetic flux through the solar surface and the extreme geoeffective events. The main ingredients for getting X-ray class flares and large interplanetary Coronal Mass Ejections (CMEs) are the build-up of electric current in the corona, the existence of magnetic free energy, magnetic energy/helicity ratio, twist, and magnetic stress in active regions (ARs). The upper limit of solar energy in the space rese…

Radiocarbon analysis of turfgrasses can help cities measure greenhouse gas emissions
Cities around the world are working to limit emissions of climate-warming greenhouse gases, but there have been few ways of measuring whether those gases are actually decreasing in any given municipality. In new research, University of California, Irvine scientists have created an effective method to measure greenhouse gas emissions around cities—something that can help local governments gauge the effectiveness of their emission-curbing programs.

Einsam vor dem Bildschirm – Studie warnt vor Lage im Land
Wer länger am Bildschirm sitzt, fühlt sich laut einer Studie häufiger einsam. Warum die Experten mehr Aufklärung über den Umgang mit digitalen Medien fordern.

New study by @… et al. finds that emissions in China and India are projected to grow much less in 2025 compared to the past decade, while emissions in the US and EU are projected to grow this year after years of decline.

Spatially non-parametric recovery of intrinsic kinematic maps in pre- to post-merger galaxies
We introduce an adaptable kinematic modelling tool called ROHSA-SNAPD, "Spatially Non-parametric Approach to PSF Deconvolution using ROHSA". ROHSA-SNAPD utilises kinematic regularisation to forward model the intrinsic emission-line flux and kinematics (velocity and linewidth) of 3D data cubes. Kinematic regularisation removes the need to assume an underlying rotation model (eg. exponential disc, tilted-ring) to deconvolve kinematic data. We evaluate the code on mock observations of simulated ga…
