An Updated Detection Pipeline for Precursor Emission in Type II Supernova 2020tlf
No full textInternational audienceWe present a new photometric pipeline for the detection of pre-supernova (pre-SN) emission in the Young Supernova Experiment (YSE) sky survey. The method described is applied to SN 2020tlf, a type II SN (SN II) with precursor emission in the last ~100 days before first light. We re-analyze the YSE griz-band light curves of SN 2020tlf and provide revised pre-explosion photometry that includes a robust list of confident detection and limiting magnitudes. Compared to the results of Jacobson-Galan et al. 2022a, this new analysis yields fewer total r/i/z-band pre-SN detections at phases > -100 days. Furthermore, we discourage the use of the blackbody modeling of the pre-explosion spectral energy distribution, the pre-SN bolometric light curve and the blackbody model parameters presented in Jacobson-Galan et al. 2022a. Nevertheless, binned photometry of SN 2020tlf confirms a consistent progenitor luminosity of ~10 erg s before explosion
Sade's theatre: pleasure, vision, masochism
No full textSade’s rehabilitation as a major Enlightenment writer has hitherto not extended to a re-evaluation of his dramatic works. With a theoretical framework inspired by psychoanalysis and dramatic theory, and attentive to eighteenth-century theoretical debates, Thomas Wynn demonstrates the value of these neglected works. This is the first study to consider the nature and implications of Sade’s dramatic aesthetic, and to define the erotic quality of spectatorship in his experimental plays. Challenging the assumption that the gaze is sadistic, the author uses insights from film theory to argue that Sade adapts contemporary theatrical texts and practice to create an aesthetic distinct from that of his novels. Rather than replicate the style of such works as Les Cent vingt journées de Sodome, Sade’s drama anticipates a masochistic model, as theorised by Theodor Reik and Gilles Deleuze. This analysis of Sadean spectatorship takes a thematic rather than chronological or text-by-text approach. The author argues that Sade, as an atheist materialist, focuses on the structural elements of theatre to produce visual pleasure rather than moral improvement, and that he elaborates an insistently visual dramatic aesthetic, a mode analogous to the linguistic saturation of the novels’ tout dire. With reference to eighteenth-century obscene drama, theatre architecture and the history of visuality, the author explores the paradox that Sade’s theatre is meant not for the stage, but for the private imagination. His visionary theatre is an example of the late eighteenth-century sublime, an aesthetic of the ineffable and the unrepresentable which, in its emphasis on the survival of the demeaned individual, structurally resembles masochism. Without deforming his technique or strategy, the author shows that Sade’s voluptuous theatre – like his fiction – addresses an individual whose sovereignty in a godless world is intimately linked to the independent imagination. This book will be of interest to all those working in eighteenth-century drama and theory of spectatorship. After studying at the University of Cambridge, Thomas Wynn completed his DPhil in French at St John’s College, Oxford in 2004. As well as teaching at the Ecole normale supérieure in Paris, he has also been a post-doctoral fellow at Lincoln College, Oxford. He has published on Sade, cinema and eighteenth-century theatre, as well as contributing to the Complete works of Voltaire. His edition of Hénault’s François II will be published shortly with the MHRA. Acknowledgements List of abbreviations Introduction: viewing pleasure 1.

Vining phase excavations on the Chattahoochee-Oconee National Forest
No full textThe Vining Phase in central Georgia is an old idea (Kelly 1938) that has new life as a result of more recent excavations in the Oconee National Forest. It was defined as a simple-stamped ceramic complex, an idea that was rejected at the time. Recent excavations suggest that sites with simple stamped pottery and small triangular points located on ridgetops in central Georgia belong to Vining (Elliott and Wynn 1991); it appears to be a Late Woodland-Early Mississippian transitional phase. Four Vining phase sites, Guthrie, Passport, Fant-Davis and Elliott, were excavated between 1988 and 1996. Here we summarize what is known about the Vining phase thus far, describe the results of these modern excavations, and discuss future research directions. This paper is based on the Summary Report (Meyers et al. 1997).Journal Articlefinal article publishe
A Carbon/Oxygen-dominated Atmosphere Days after Explosion for the "Super-Chandrasekhar" Type Ia SN 2020esm
No full textSeeing pristine material from the donor star in a type Ia supernova (SN Ia) explosion can reveal the nature of the binary system. In this paper, we present photometric and spectroscopic observations of SN 2020esm, one of the best-studied SNe of the class of "super-Chandrasekhar" SNe Ia (SC SNe Ia), with data obtained 12 to +360 days relative to peak brightness, obtained from a variety of ground- and space-based telescopes. Initially misclassified as a type II supernova, SN 2020esm peaked at M-B = -19.9 mag, declined slowly (Delta m(15)(B) = 0.92 mag), and had particularly blue UV and optical colors at early times. Photometrically and spectroscopically, SN 2020esm evolved similarly to other SC SNe Ia, showing the usual low ejecta velocities, weak intermediate-mass elements, and the enhanced fading at late times, but its early spectra are unique. Our first few spectra (corresponding to a phase of greater than or similar to 10 days before peak) reveal a nearly pure carbon/oxygen atmosphere during the first days after explosion. This composition can only be produced by pristine material, relatively unaffected by nuclear burning. The lack of H and He may further indicate that SN 2020esm is the outcome of the merger of two carbon/oxygen white dwarfs. Modeling its bolometric light curve, we find an Ni-56 mass of 1.23(-0.14)(+0.14) M-circle dot and an ejecta mass of 1.75(-0.20)(+0.32)M(circle dot), in excess of the Chandrasekhar mass. Finally, we discuss possible progenitor systems and explosion mechanisms of SN 2020esm and, in general, the SC SNe Ia class.</p

Cooling rates of neutron stars and the young neutron star in the Cassiopeia A supernova remnant
No full textWe explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke that the thermal radiation of this star is well described by a carbon atmosphere model and the emission comes from the entire stellar surface. Starting from neutron star cooling theory, we formulate a robust method to extract neutrino cooling rates of thermally relaxed stars at the neutrino cooling stage from observations of thermal surface radiation. We show how to compare these rates with the rates of standard candles – stars with non-superfluid nucleon cores cooling slowly via the modified Urca process. We find that the internal temperature of standard candles is a well-defined function of the stellar compactness parameter x=rg/R, irrespective of the equation of state of neutron star matter (R and rg are circumferential and gravitational radii, respectively). We demonstrate that the data on the Cassiopeia A neutron star can be explained in terms of three parameters: f?, the neutrino cooling efficiency with respect to the standard candle; the compactness x; and the amount of light elements in the heat-blanketing envelope. For an ordinary (iron) heat-blanketing envelope or a low-mass (? 10?13 M?) carbon envelope, we find the efficiency f?? 1 (standard cooling) for x? 0.5 and f?? 0.02 (slower cooling) for a maximum compactness x? 0.7. A heat blanket containing the maximum mass (?10?8 M?) of light elements increases f? by a factor of 50. We also examine the (unlikely) possibility that the star is still thermally non-relaxe
