Understanding the relationship between the UV/optical emission from the accretion disc and the X-ray emission associated with the corona is vital to understand differing AGN accretion states and thus the growth phases of black holes. The optical-to-X-ray spectral slope describes the relative strength of the hard X-rays to the accretion disc emission which peaks in the UV. The well-established...

We present a UV parameter space as a spectroscopical sequence to organize quasars along the spectral diversity. In the optical range, quasar spectral diversity has been analyzed using the so-called Eigenvector 1 (E1) "main sequence", which involves the FWHM of the broad component of Hb and the flux ratio of FeII and Hb. The E1 also provides information on the physical conditions of the optical...

In this talk we will give an overview about how we plan to calibrate the atmospheric parameters and abundances of the first data release of MWM. To assess this accuracy and precision of these parameters, we need to compare the results of Astra with a validation set that represents well the different stellar types observed by the MWM and that is well-characterised. We are assembling and...

In the study of galactic archeology, the lack of reliable stellar ages often impairs the capability to accurately explain the evolution of our galaxy. To date, NASA's Kepler mission has been considered the gold standard for the most precise asteroseismic ages, despite data only being available for a small portion of the sky. With TESS’s all-sky photometry now available, we can expand the...

We present a summary of SDSS V Fiber Positioning System (FPS) operations through the present, including roughly one and a half years at Apache Point Observatory (APO) and 10 months at Las Campanas Observatory. We provide a high level summary of progress at the robot-configuration level, as well as a brief summary of progress towards specific science programs. We further compare to simulations...
