We present 1.8 yr of near-daily Swift monitoring of the bright, strongly variable Type 1 active galactic nucleus (AGN) Fairall 9. Totaling 575 successful visits, this is the largest such campaign reported to date. Variations within the UV/optical are

We examine the long-term history of the optical spectrum of the extremely variable Active Galactic Nucleus (AGN) MKN 110. By combining various archival data with new data, we cover an unprecedented long period of $\sim$30 years (1987 - 2019). We find

The UV response to X-ray outbursts suggests a more complex reprocessing geometry than a standard disc ', Monthly Notices of the Royal Astronomical Society, vol. 519, no. 3, pp. 3903-3922 . https://doi.org/10.1093/mnras/stac3515
Mrk 590 is a known changing-look AGN which almost turned off in 2012, and then in 2017 partially re-ignited into a repeat flaring state, unusual for an AGN. Our \emph{Swift} observations since 2013 allow us to characterise the accretion-generated emi

BACKGROUND AND PURPOSE: The rehabilitation of post-intensive care syndrome and critical illness myopathy has been well documented.1,2 However, the recent wave of individuals recovering from COVID-19 demonstrate unique treatment considerations based o

Quasar broad emission lines are largely powered by photoionization from the accretion continuum. Increased central luminosity will enhance line emissivity in more distant clouds, leading to increased average distance of the broad-line-emitting clouds

The development of laser wakefield accelerators (LWFA) over the past several years has led to an interest in very compact sources of X-ray radiation – such as “table-top” free electron lasers. However, the use of conventional undulators using p

Objectives were to determine the effects of an industry-typical (Control) and 3 “gourmet” (Grey sea, Pink rock, and unrefined Rock) salts on the processing yields and shelf-life of moisture-enhanced pork loins. Loins (n = 41) were injected with a

Some Eurasian shrubs, including species of Lonicera, have become invasive in North America. Recently, Lonicera caerulea cultivars have been developed from Eurasian germplasm and promoted for North American markets as honeyberry, haskap, or sweetberry

The objective was: 1) to characterize the effect of marketing group on fresh and cured ham quality, and 2) to determine which fresh ham traits correlated to cured ham quality traits. Pigs raised in 8 barns representing 2 seasons (hot and cold) and 2
