Description
Ground-based multichannel photometry of integral sunlight has been obtained at Izaña (Tenerife) during three months in 1984 with a photometer built at ESTEC. Power spectra of solar irradiance variations of individual days show power in the 5 min band just above noise at a level comparable to the one found from the SMM data (Woodard and Hudson, 1983). Previous similar ground work had never achieved the signal level required at the 5 min interval. When combining the best 7 contiguous days of data, the signature of p mode solar oscillations spectra appears, but individual identification is difficult due to a low signal-to-noise ratio.

    Constraints on compact objects from the Dark Energy Survey 5-yr supernova sample
    Gravitational lensing magnification of Type Ia supernovae (SNe Ia) allows information to be obtained about the distribution of matter on small scales. In this paper, we derive limits on the fraction $\alpha$ of the total matter density in compact objects (which comprise stars, stellar remnants, small stellar groupings, and primordial black holes)

    Multiband Optical Variability of the Blazar 3C 454.3 on Diverse Timescales
    Due to its peculiar and highly variable nature, the blazar 3C 454.3 has been extensively monitored by the WEBT team. Here, we present for the first time these long-term optical flux and color variability results using data acquired in B, V, R, and I bands over a time span of about two decades. We include data from WEBT collaborators and public

    Calibrating the Clock of JWST
    JWST, despite not being designed to observe astrophysical phenomena that vary on rapid timescales, can be an unparalleled tool for such studies. If timing systematics can be controlled, JWST will be able to open up the subsecond infrared timescale regime. Rapid time-domain studies, such as lag measurements in accreting compact objects and solar
