Fünf Sterne deluxe und das Philharmonische Orchester Kiel am Freitag Abend auf dem Rathausplatz bei der Kieler Woche. Super guten Konzert aber es war auch echt voll. Uns so viele Erinnerungen an jüngere Tage ... 🎤

Wir haben gestern Abend mit den Kids zusammen KPop Demon Hunters auf deutsch geguggt, nachdem Bee und ich den vorher schon gesehen haben.
Film ist zwar auf deutsch aber die Lieder sind immer noch englisch. Also ab und zu ein paar Zeilen live übersetzen.
Aber beim letzten Lied (What it sound like) ging das nicht, weil Kloß im Hals. XD Ich bin ein Sucker für Zusammenfinden-Kitsch. 😅

Rubidium Abundances in Cool Giants from High-Resolution H-band Spectra: A New Diagnostic for Galactic Chemical Evolution
The Galactic Center and inner disk of the Milky Way contain complex stellar populations obscured by heavy dust extinction. To study their chemical composition, high-resolution near-infrared (near-IR) spectroscopy is necessary. Expanding the set of elements measurable in the near-IR, especially neutron-capture elements, improves our ability to trace nucleosynthesis and Galactic chemical evolution. This work aims to identify and characterize a spectral line suitable for determining rubidium (Rb) …

Ein schönes Abendessen mit meiner Frau und meiner Schwiegermutter in einem recht kleinen, familiengeführten Restaurant in Willich. Die italienische Wirtin schreibt alle zwei Tage eine neue, kleine Speisekarte von Hand. "Alles frisch". Daran habe ich keinen Zweifel.

Transient star B/R ratio and star formation in $z\gtrsim 1$ lensed galaxies
The extreme magnification from galaxy clusters and microlenses therein allows the detection of individual, luminous stars in lensed galaxies as transient events, and hence provides a valuable window into the high mass stellar population in $z>1$ galaxies. As these bright stars can only be formed at specific ages, the relative abundance of transient events at blue (B) and red (R) optical wavelengths ($B/R$ ratio) can provide insights into the star formation history of lensed galaxies. Here, we f…

Look, all I'm saying is, this Kennedy psychopath is trying to kill our children. I feel like self-defense rules apply. Isn't it time for a new HHS Secretary anyway?

New Trump vaccine policy limits access to COVID shots
Federal health officials will no longer routinely approve annual COVID-19 shots for younger adults and children who are healthy. Companies that want to market their vaccines to those Americans will need to conduct large, new studies, the Food and Drug Administration said Tuesday. It’s a major shift in FDA’s approach to updating vaccines that protect against the virus. It comes as Health Secretary Robert F. Kennedy Jr. and his appointees continue to scrutinize the use of vaccines for a numbe…

Dark Matter Detector Radioimpurities $^{129}$I and $^{210}$Pb Measured with Accelerator Mass Spectrometry
Sodium iodide crystals doped with thallium NaI(Tl) can be used as detector material for direct dark matter detection by taking advantage of their particle detection properties of scintillation. In order to achieve this, it is crucial that these crystals are of ultra-high purity. Radioimpurities within the crystals may potentially mimic dark matter signals and thus must be quantified, minimised where possible and distinguished from real events. Abundances of radionuclides $^{129}$I and $^{210}$P…
