SILCC -- IX. The multi-phase interstellar medium at low metallicity
The gas-phase metallicity affects heating and cooling processes in the star-forming galactic interstellar medium (ISM) as well as ionising luminosities, wind strengths, and lifetimes of massive stars. To investigate its impact, we conduct magnetohydrodynamic simulations of the ISM using the FLASH code as part of the SILCC project. The simulations assume a gas surface density of 10 M$_\odot$ pc$^{-2}$ and span metallicities from 1/50 Z$_\odot$ to 1 Z$_\odot$. We include non-equilibrium thermo-ch…

Yes, at German discount supermarkets, you can purchase a do-it-yourself 'Balkonsolar' system and battery. Simply plug it in and you're ready to go.
However, Aldi Australia offers complete systems: 6 kW solar, a 5.5 kW inverter and a 10 kWh LFP battery, fully installed for AU$7,000 (€4,000)!

Supermarket giant expands rooftop solar and battery offer
Budget supermarket chain Aldi is expanding its residential solar business, opening up sales of its rooftop PV and battery energy storage packages to customers in Australia’s eastern states after a trial in Victoria.

Neutrino signal from the hadron-quark phase transition in the conversion of Neutron Stars into Quark Stars
We calculate in a 1D General Relativistic (GR) hydrodynamic simulation the neutrino luminosity in an astrophysical scenario where a neutron star (NS) displays a hadron-quark phase transition (HQPT) into a Quark Star (QS). Deconfinement is triggered once the central density exceeds a critical threshold above $\sim 3n_0$ being $n_0$, saturation density. We use descriptions based on DD2 and the MIT Bag model equations of state (EOSs). We account for neutrinos using a microphysics forward emission …

Fast radio bursts shed light on direct gravity test on cosmological scales
A key measure of gravity is the relation between the Weyl potential $Ψ+Φ$ and the matter overdensity $δ_m$, capsulized as an effective gravitational constant $G_{\rm light}$ for light motion. Its value, together with the possible spatial and temporal variation, is essential in probing physics beyond Einstein gravity. However, the lack of an unbiased proxy of $δ_m$ prohibits direct measurement of $G_{\rm light}$. We point out that the equivalence principle ensures the dispersion measure (DM)…

EU bestellt Botschafter ein
Die EU hat anlässlich der Verletzung des polnischen Luftraums durch russische Drohnen die Botschafter von Russland und Belarus einbestellt. "Wir haben unmissverständlich zum Ausdruck gebracht, dass diese rücksichtslose Handlung eine ernsthafte Eskalation seitens Russlands darstellt", teilte ein EU-Beamter in Brüssel mit.

JWST imaging of omega Centauri: II. Evidence for a split white dwarf cooling sequence in the near-infrared
We present a detailed analysis of the white dwarf cooling sequence (WD CS) in omega Centauri based on combined Hubble Space Telescope (HST) and JWST observations. Our analysis confirms the previously reported split - based on HST observations in ultraviolet filters - in the upper part of the WD CS, consistent with the presence of two distinct WD populations, and extends it to a significantly fainter and cooler limit (down to ~8000 K), corresponding to cooling ages of about 1 Gyr. We used artifi…

A thermonuclear supernova interacting with hydrogen- and helium-deficient circumstellar material. SN 2020aeuh as a SN Ia-CSM-C/O?
Identifying the progenitors of thermonuclear supernovae (Type Ia supernovae; SNe Ia) remains a key objective in contemporary astronomy. The rare subclass of SNe Ia that interacts with circumstellar material (Type Ia-CSM) allows for studies of the progenitor's environment before explosion, and generally favours single-degenerate progenitor channels. The case of SN Ia-CSM PTF11kx clearly connected thermonuclear explosions with hydrogen-rich CSM-interacting events, and the more recent SN 2020eyj c…

Effect of stochastic kicks on primordial black hole abundance and mass via the compaction function
We study stochastic effects in viable ultra-slow-roll inflation models that produce primordial black holes. We consider asteroid, solar, and supermassive black hole seed masses. In each case, we simulate $10^8$ patches of the universe that may collapse into PBHs. In every patch, we follow $4\times10^4$ momentum shells to construct its spherically symmetric profile from first principles, without introducing a window function. We include the effects of critical collapse and the radiation era tran…
