Deriving physical parameters of unresolved star clusters. IX. Sky background effects in the aperture photometry
The aperture photometry method is a powerful tool that enables us to study large star cluster systems efficiently. However, its accuracy depends on various factors, including the stochasticity of the stellar initial mass function and variations in the sky background. Previously, in the eighth paper of this series, we established the best achievable limits of the aperture photometry method for star cluster studies in the local universe. The aim of this study is to determine how the sky backgroun…

Deriving physical parameters of unresolved star clusters. VIII. Limits of aperture photometry for star cluster studies
Recently, it has been noticed that the discrepancies in the integrated colour indices (CIs) between star clusters and models are mostly due to the projection of bright stars in the apertures. In order to reduce this problem, the method of adaptive aperture photometry has been proposed. This method has been applied to star clusters from the M 31 Panchromatic Hubble Andromeda Treasury (PHAT) survey, and studies show that the adaptive aperture photometry performs better than the conventional appro…

Falls es auf der #Cityroute Süd irgendeinen Hinweis oder eine Umleitung vor diesem abrupten Totalblock gab, kann er jedenfalls nicht sehr auffällig gewesen sein. Ich nehme eher an, dass in der #Fahrradstadt #Karlsruhe

Born to be Starless: Revisiting the Missing Satellite Problem
The massive Local Group galaxies both host substantially fewer satellites than the subhalos expected from the cold dark matter paradigm, and the recent investigations have highlighted the interplay between baryons and dark matter. We investigate the processes that make subhalos starless, using high-resolution cosmological simulations. We found that the number of satellites around Milky Way analogs closely aligns with observations, which accords with recent studies. In our simulations, the major…

Ich wurde wegen großflächiger Baumaßnahmen in #Karlsruhe eben am Europaplatz aus der #Tram 2 geworfen. So weit so gut (war ja angekündigt).
Meinen freundlichen Hinweis, es wäre da möglicherweise kundenfreundlicher, den (elektronischen) Zielanzeiger der Bahn "Europaplatz" statt "Knieli…
