This article examines the significance of a highly unusual stone statue discovered at Teynham, Kent, depicting a triton and a ketos. It discusses the context of the find in what appears to be a mausoleum complex adjacent to Watling Street. It provides a detailed description of the statue itself, alongside a petrological study, and places this in the context of other depictions of marine deities, particularly of tritons, in Britain and beyond. The article considers how the sculpture might have been placed on the exterior or interior of the tomb. It also discusses the possible occupant of the mausoleum (perhaps a villa owner or sailor), taking into account the possible symbolic value of the triton, either as signifier of afterlife beliefs or biographical achievement, as well as the ritual treatment of the statue after the tomb was dismantled. The wider context of the Teynham mausoleum is then analysed in terms of its location and form in relation to comparable monuments found in south-east England and better preserved tombs on the continent.

We present the third data release from the Parkes Pulsar Timing Array (PPTA) project. The release contains observations of 32 pulsars obtained using the 64-m Parkes ‘Murriyang’ radio telescope. The data span is up to 18 yr with a typical cadence of 3 weeks. This data release is formed by combining an updated version of our second data release with $\sim$3 yr of more recent data primarily obtained using an ultra-wide-bandwidth receiver system that operates between 704 and 4032 MHz. We provide calibrated pulse profiles, flux density dynamic spectra, pulse times of arrival, and initial pulsar timing models. We describe methods for processing such wide-bandwidth observations and compare this data release with our previous release.

Beaded rims are a characteristic feature of late Roman silver plate vessels, many of which have been found in British treasures including Mildenhall and Traprain Law. This paper discusses how these beaded rims provide insights into the production of silver plate, adding to what little is known of silver plate workshops. Vessels in the Mildenhall treasure provide a case study, after which measurements from beaded rims on other treasures from Roman Britain and the western Roman Empire are compared and discussed.

We describe 14 yr of public data from the Parkes Pulsar Timing Array (PPTA), an ongoing project that is producing precise measurements of pulse times of arrival from 26 millisecond pulsars using the 64-m Parkes radio telescope with a cadence of approximately 3 weeks in three observing bands. A comprehensive description of the pulsar observing systems employed at the telescope since 2004 is provided, including the calibration methodology and an analysis of the stability of system components. We attempt to provide full accounting of the reduction from the raw measured Stokes parameters to pulse times of arrival to aid third parties in reproducing our results. This conversion is encapsulated in a processing pipeline designed to track provenance. Our data products include pulse times of arrival for each of the pulsars along with an initial set of pulsar parameters and noise models. The calibrated pulse profiles and timing template profiles are also available. These data represent almost 21 000 h of recorded data spanning over 14 yr. After accounting for processes that induce time-correlated noise, 22 of the pulsars have weighted root-mean-square timing residuals of $<\!\!1\,\mu\text{s}$ in at least one radio band. The data should allow end users to quickly undertake their own gravitational wave analyses, for example, without having to understand the intricacies of pulsar polarisation calibration or attain a mastery of radio frequency interference mitigation as is required when analysing raw data files.

We describe an ultra-wide-bandwidth, low-frequency receiver recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage from 704 to 4032 MHz. For much of the band ( ${\sim}60\%$ ), the system temperature is approximately 22 K and the receiver system remains in a linear regime even in the presence of strong mobile phone transmissions. We discuss the scientific and technical aspects of the new receiver, including its astronomical objectives, as well as the feed, receiver, digitiser, and signal processor design. We describe the pipeline routines that form the archive-ready data products and how those data files can be accessed from the archives. The system performance is quantified, including the system noise and linearity, beam shape, antenna efficiency, polarisation calibration, and timing stability.

The hoard of silver plate known as the Vinkovci treasure (or the Cibalae treasure, after the Roman name for the town) was discovered on March 23, 2012, during rescue excavations in the town of Vinkovci (Colonia Aurelia Cibalae) in the Vukovar-Srijem county of E Croatia (fig. 1). It is one of the most significant late Roman discoveries of the new millennium, and the first major 4th-c. A.D. assemblage of silver plate to be unearthed for at least half a century (the Seuso treasure was probably found in the late 1970s, and although new pieces of the Kaiseraugst treasure emerged in the 1990s the original discovery was made in 1961). This interim report on the treasure is based upon the results of research conducted by the authors in the 4 years that have passed since it came to light.

An Ensemble Pulsar Time Scale (EPT) is derived based on the Pulsar Timing Array. It is interesting to compare the EPT with the TT terrestrial time scale, and get many new realization on the pulsar time scale and the algorithm. Some future interesting applications of the EPT are described and discussed.

A strain of the alfalfa leafcutter bee, Megachile pacifica Panzer, that has produced less than 1% second-generation adults for 3 consecutive years was produced by selection against bivoltinism. The selection process also resulted in the production of bees that reproduced at a much higher rate than the unselected parent stock.

The ‘William Allen box’ is a rare survival of a collection of antiquities, mostly of Roman date, collected in the Victorian period. This paper discusses the identity and life of the collector and some of the more notable objects before examining the provenance of some of the material, in particular the findspots ‘Ad Fines’ and ‘Croydon’. The importance of the collection in the context of the antiquarian age in which it was assembled is also discussed.
