Tag 11 von #MeinCamino2025
Endlich mal ein entspannter Tag. 31 km ohne große Höhenunterschiede von #Molinaseca nach Villafranca del Bierzo. Dort gibt es in heiligen Jakobusjahren beim Durchschreiten einer Gnadentüre Ablass für alle, die es aus Krankheitsgründen nicht mehr bis Santiago …

AstroQ: Automated Scheduling of Cadenced Astronomical Observations
Astronomy relies heavily on time domain observations. To maximize the scientific yield of such observations, astronomers must carefully match the observational cadence to the phenomena of interest. This presents significant scheduling challenges for observatories with multiple large programs, each with different cadence needs. To address this challenge, we developed AstroQ, an automated framework for scheduling cadenced observations. We tested this on a suite of Doppler exoplanet programs at Ke…

Analysis of the evolution of terrestrial relief through inverse elevation transition
Through the examination of the Theory of Seismic Energy and the Theory of Volcanic Energy, we understand that the interaction of internal and external energies in favourable terrain has led to countless transformations over geological time frames. Therefore, this research aims to understand the evolution of the Earth's surface based on the theories proposed by Claudio Valverde Ramirez. This study introduces the concept of inverse elevation transition, which explains the formation of mountains, …

Generalization of Ramanujan's formula for the sum of half-integer powers of consecutive integers via formal Bernoulli series
Faulhaber's formula expresses the sum of the first $n$ positive integers, each raised to an integer power $p\geq 0$ as a polynomial in $n$ of degree $p+1$. Ramanujan expressed this sum for $p\in\{\frac12,\frac32,\frac52,\frac72\}$ as the sum of a polynomial in $\sqrt{n}$ and a certain infinite series. In the present work, we explore the connection to Bernoulli polynomials, and by generalizing those to formal series, we extend the Ramanujan result to all positive half-integers $p$.

Echo mapping of the black hole accretion flow in NGC 7469
Reverberation mapping (RM) can measure black hole accretion disc sizes and radial structure through observed time lags that should increase with wavelength as $τ\proptoλ^{4/3}$. Our 250-day RM campaign on NGC 7469 combines sub-day cadence 7-band photometry from the Las Cumbres Observatory robotic telescopes and weekly X-ray and UVOT data from Swift. By fitting these light curves, we measure the spectral energy distribution of the variable accretion disc and inter-band lags of just 1.5 days ac…

Weil hier gerade die Bekämpfung von Mobbying Thema ist:
Die @… hat mich an die (zumindest bei jüngeren Kindern) vielversprechendste Methode erinnert, wie man Mobbying abdrehen kann.
Der "No Blame Approach":
#Mobbying

#GoingDark und kein Ende. Die neueste Schnüffeloffensive der #EU-Kommission zeigt wieder einmal, dass es den vielberufenen Systemwettbewerb gar nicht gibt, denn eigentlich wollen alle chinesisch werden: Kapital und Kontrolle maximal glücklich zu verbinden, das ist doch fein.
