ABSTRACTOptical imaging polarimetry was conducted on the hydrogen poor superluminous supernova 2020znr during three phases after maximum light (≈ +34 d, +288 d, and +289 d). After instrumental and interstellar polarization correction, all measurements are consistent with null-polarization detection. Modelling the light curve with a magnetar spin-down model shows that SN2020znr has similar magnetar and ejecta parameters to other SLSNe. A comparison of the best-fitting values discussed in the literature on SN 2017egm and SN 2015bn, two hydrogen poor SLSNe showing an increase of polarization after maximum light, suggests that SN 2020znr has higher mass ejecta that may prevent access to the geometry of the inner ejecta with optical polarimetry. The combined information provided by spectroscopy and light-curve analysis of type I SLSNe may be an interesting avenue to categorize the polarization properties of this class of transients. This approach would require to expand the sample of SLSNe polarimetry data currently available with early and late time epochs new measurements.
The Thresher: Lucky imaging without the waste
Authors: Hitchcock J A , Bramich D M , Foreman-Mackey D , Hogg David W , Hundertmark M 
Published: February 2022

ABSTRACT
In traditional lucky imaging (TLI), many consecutive images of the same scene are taken with a high frame-rate camera, and all but the sharpest images are discarded before constructing the final shift-and-add image. Here, we present an alternative image analysis pipeline – The Thresher – for these kinds of data, based on online multi-frame blind deconvolution. It makes use of all available data to obtain the best estimate of the astronomical scene in the context of reasonable computational limits; it does not require prior estimates of the point-spread functions in the images, or knowledge of point sources in the scene that could provide such estimates. Most importantly, the scene it aims to return is the optimum of a justified scalar objective based on the likelihood function. Because it uses the full set of images in the stack, The Thresher outperforms TLI in signal-to-noise ratio; as it accounts for the individual-frame PSFs, it does this without loss of angular resolution. We demonstrate the effectiveness of our algorithm on both simulated data and real Electron-Multiplying CCD images obtained at the Danish 1.54-m telescope (hosted by ESO, La Silla). We also explore the current limitations of the algorithm, and find that for the choice of image model presented here, non-linearities in flux are introduced into the returned scene. Ongoing development of the software can be viewed at https://github.com/jah1994/TheThresher.
The velocity distribution of white dwarfs in Gaia EDR3
Authors: Mikkola Daniel , McMillan Paul J , Hobbs David , Wimarsson John 
Published: February 2022

ABSTRACT
Using a penalized maximum likelihood, we estimate, for the first time, the velocity distribution of white dwarfs in the solar neighbourhood. Our sample consists of 129 675 white dwarfs within 500 pc in Gaia Early Data Release 3. The white dwarf velocity distributions reveal a similar structure to the rest of the solar neighbourhood stars, reflecting that white dwarfs are subject to the same dynamical processes. In the velocity distribution for three magnitude-binned subsamples, we, however, find a novel structure at (U, V) = (7, −19) km s−1 in fainter samples, potentially related to the Coma Berenices stream. We also see a double-peaked feature in U − W at U ≈ −30 km s−1 and in V − W at V ≈ −20 km s−1 for fainter samples. We determine the velocity distribution and velocity moments as a function of absolute magnitude for two samples based on the bifurcation identified in Gaia Data Release 2 in the colour–magnitude diagram. The brighter, redder sequence has a larger velocity dispersion than the fainter, bluer sequence across all magnitudes. It is hard to reconcile this kinematic difference with a bifurcation caused purely by atmospheric composition, while it fits neatly with a significant age difference between the two sequences. Our results provide novel insights into the kinematic properties of white dwarfs and demonstrate the power of analytical techniques that work for the large fraction of stars that do not have measured radial velocities in the current era of large-scale astrometric surveys.
The strongly irradiated planets in Praesepe

Published: February 2022

ABSTRACT
We present an analysis of XMM–Newton observations of four stars in the young (670 Myr) open cluster Praesepe. The planets hosted by these stars all lie close in radius–period space to the radius–period valley and/or the Neptunian desert, two features that photoevaporation by X-ray and extreme ultraviolet (EUV) photons could be driving. Although the stars are no longer in the saturated regime, strong X-ray and extreme ultraviolet irradiation is still ongoing. Based on EUV time evolution slopes, we derived in a previous paper, in all four cases, two-thirds of their EUV irradiation is still to come. We compare the XMM–Newton light curves to those simultaneously measured with K2 at optical wavelengths, allowing us to search for correlated variability between the X-ray and optical light curves. We find that the X-ray flux decreases and flattens off while the optical flux rises throughout for K2-100, something that could result from active regions disappearing from view as the star spins. Finally, we also investigate possible futures for the four planets in our sample with simulations of their atmosphere evolution still to come, finding that complete photoevaporative stripping of the envelope of three of the four planets is possible, depending on the current planet masses.
Emulating Sunyaev–Zeldovich images of galaxy clusters using autoencoders
Authors: Rothschild Tibor , Nagai Daisuke , Aung Han , Green Sheridan B , Ntampaka Michelle , ZuHone John 
Published: February 2022

ABSTRACT
We develop a machine-learning (ML) algorithm that generates high-resolution thermal Sunyaev–Zeldovich (SZ) maps of novel galaxy clusters given only halo mass and mass accretion rate (MAR). The algorithm uses a conditional variational autoencoder (CVAE) in the form of a convolutional neural network and is trained with SZ maps generated from the IllustrisTNG simulation. Our method can reproduce many of the details of galaxy clusters that analytical models usually lack, such as internal structure and aspherical distribution of gas created by mergers, while achieving the same computational feasibility, allowing us to generate mock SZ maps for over 105 clusters in 30 s on a laptop. We show that the model is capable of generating novel clusters (i.e. not found in the training set) and that the model accurately reproduces the effects of mass and MAR on the SZ images, such as scatter, asymmetry, and concentration, in addition to modelling merging sub-clusters. This work demonstrates the viability of ML-based methods for producing the number of realistic, high-resolution maps of galaxy clusters necessary to achieve statistical constraints from future SZ surveys.
IAGS: Inferring Ancestor Genome Structure under a Wide Range of Evolutionary Scenarios
Authors: Gao Shenghan , Yang Xiaofei , Sun Jianyong , Zhao Xixi , Wang Bo , Ye Kai 
Published: February 2022

Abstract
Significant improvements in genome sequencing and assembly technology have led to increasing numbers of high-quality genomes, revealing complex evolutionary scenarios such as multiple whole-genome duplication events, which hinders ancestral genome reconstruction via the currently available computational frameworks. Here, we present the Inferring Ancestor Genome Structure (IAGS) framework, a novel block/endpoint matching optimization strategy with single-cut-or-join distance, to allow ancestral genome reconstruction under both simple (single-copy ancestor) and complex (multicopy ancestor) scenarios. We evaluated IAGS with two simulated data sets and applied it to four different real evolutionary scenarios to demonstrate its performance and general applicability. IAGS is available at https://github.com/xjtu-omics/IAGS.
H3K36 methylation and DNA-binding both promote Ioc4 recruitment and Isw1b remodeler function

Published: February 2022

Abstract
The Isw1b chromatin-remodeling complex is specifically recruited to gene bodies to help retain pre-existing histones during transcription by RNA polymerase II. Recruitment is dependent on H3K36 methylation and the Isw1b subunit Ioc4, which contains an N-terminal PWWP domain. Here, we present the crystal structure of the Ioc4-PWWP domain, including a detailed functional characterization of the domain on its own as well as in the context of full-length Ioc4 and the Isw1b remodeler. The Ioc4-PWWP domain preferentially binds H3K36me3-containing nucleosomes. Its ability to bind DNA is required for nucleosome binding. It is also furthered by the unique insertion motif present in Ioc4-PWWP. The ability to bind H3K36me3 and DNA promotes the interaction of full-length Ioc4 with nucleosomes in vitro and they are necessary for its recruitment to gene bodies in vivo. Furthermore, a fully functional Ioc4-PWWP domain promotes efficient remodeling by Isw1b and the maintenance of ordered chromatin in vivo, thereby preventing the production of non-coding RNAs.
Tristan Murail’s Musical Poetics
Authors: Cagney Liam 
Published: February 2022

Abstract
This chapter examines Murail’s music from his late 1960s student works to the highly sophisticated works of the 2000s through the notion of poetics. It draws on Paul Valéry’s concept of poetics, which sought to address how the artist’s aesthetic aims can require the consequent development of an appropriate technical compositional framework. Murail’s musical poetics, as they developed, are shown to have at times a neo-Symbolist character. Through examination of Murail’s music and thinking, the chapter identifies four stages in the development of his poetics: a first, apprentice stage moving away from serialism; a second stage corresponding to the initial emergence of French spectralism; a third stage taking advantage of computers to establish a quasi-systematic spectral harmonic framework; and a final (current) stage using the previous developments to reengage with classical tradition. The chapter concludes with a brief discussion of Murail’s turn in his most recent music to the interrelation of sound, psyche, and the self.
Hugues Dufourt and the Origins of His World
Authors: Nonken Marilyn 
Published: February 2022

Abstract
This chapter explores the foundational principles of the spectral attitude, examining the contributions of Hugues Dufourt in relation to his training as a philosopher and his composition L’Origine du monde (2004). The chapter considers Gustave Courbet’s painting of the same name, as the intersection of these two works provides a vantage point from which to consider a history of realism and functional aesthetics. In a discussion informed by the writings of Martin Seel, the chapter suggests how Dufourt, by linking his composition to Courbet, directs the listener to interact with objects of sensuous perception and objects of aesthetic imagination, with an eye towards elective affinities among artists that transcend time, place, and style.
Degrees of Responsibility
Authors: Coates D. Justin 
Published: February 2022

Abstract
Any adequate theory of moral responsibility must account for the fact that agents can be more or less morally responsible for their actions. To do this, a theory must answer two distinct questions. The first of these questions concerns what exactly it means to say that one agent is more (or less) responsible for her actions than some other agent who has also performed an action of that type. The second of these questions concerns the conditions that can affect or alter the degree to which an agent is more (or less) morally responsible for what she’s done. This chapter explores possible answers to these two questions, and although this isn’t all there is to say about degrees of responsibility, it is the bare minimum that adequate theories of moral responsibility owe us.
Relationships and Responsibility
Authors: Nelkin Dana Kay 
Published: February 2022

Abstract
This article critically explores three debates about ways in which responsibility and personal relationships have been thought to be linked. First, there is a question of whether valuable human relationships such as friendship in some way presuppose responsible agency on the part of their participants. Those who have argued in favor of such a connection have taken a variety of approaches: For example, friendship has been claimed to require responsible agency in virtue of the fact that it requires susceptibility to the reactive attitudes such as indignation that presuppose responsibility; friendship has been claimed to be more valuable when chosen by exercising the capacity of free choice constitutive of responsible agency; and friendship has been claimed to be constituted by special obligations that themselves require the kind of free agency necessary for responsibility. Second, there is a question of whether the conditions of responsible agency must make essential reference to relationships; for example, on one prominent view, to take someone to be blameworthy is to take their attitudes to be such as to have impaired one’s relationship with them. Finally, there is a question of whether and how our particular relationships to others affects whether and how it is all-things considered permissible to blame them. This last question falls into what has come to be known as the “ethics of blame.”
Responsibility and Consciousness
Authors: King Matt , Carruthers Peter 
Published: February 2022

Abstract
It is natural to think that consciousness is in some sense required for responsibility. A lack of awareness typically excuses (or at least mitigates blame). Meanwhile, the emerging consensus from the cognitive sciences suggests that much of our mental lives is unconscious. This chapter examines the prospects for a consciousness requirement against the backdrop of these findings. It defends the view that while consciousness is important for responsibility, it is not a necessary condition. Additionally, the chapter provides a framework for understanding the ways in which consciousness might be relevant for responsibility, and it critically assesses one leading defense of a consciousness requirement. Particular attention is paid to three kinds of cases involving unconscious processes: automaticism (like sleepwalking), forgetting, and implicit bias. The chapter concludes by considering one possible implication of the view defended: that the traditional use of consciousness in marking important divisions of mens rea in the criminal law may be misguided.
Responsibility and Reactive Attitudes
Authors: Wallace R. Jay 
Published: February 2022

Abstract
This chapter explores the role of the reactive attitudes in our practices of holding people morally responsible for what they do. Reactive attitudes include resentment, indignation, guilt, and other emotions that emerge in the context of interpersonal relationships. Questions addressed in the contribution include the following: What are the distinguishing features of the reactive attitudes as a class? Should they be understood essentially as forms of angry disapprobation, or in a more relaxed way that includes less judgmental attitudes? What is the role of the reactive attitudes in relation to the phenomenon of moral blame? Is it possible for people to opt out of the reactive attitudes altogether, or are they naturally given to us with our involvement in social relations? What are the standards to which reactive emotions are answerable? How might reactive attitudes be overcome, for example, through forgiveness, or when they are ethically problematic (as in cases of hypocrisy)? What are the implications of the reactive attitudes for traditional debates about the conditions of moral responsibility? The chapter engages with P. F. Strawson’s lecture “Freedom and Resentment,” and with some of the more recent work that has been inspired by this seminal contribution to the modern debate about moral responsibility.
Ordinary Rituals
Authors: Keck Frédéric 
Published: February 2022

Abstract
This chapter, reading Goffman’s Interaction Ritual together with Durkheim’s Elementary Forms of Religious Life and George Herbert Mead’s Mind, Self and Society, shows how taking his use of pragmatism and ethology into account establishes a more complex sociological genealogy from Durkheim to Goffman. Goffman transforms the Durkheimian conception of ritual by linking extraordinary ceremonies of primitive groups to ordinary interactions between urban individuals. The concepts of the sacred and the symbolic that are at the heart of Durkheim’s sociology are thus challenged through Goffman’s concept of ordinary ritual; but despite his reference to pragmatism, Goffman retains the formalist quality of Durkheim’s concepts.
Death in Vegas
Authors: Arnold Gina 
Published: February 2022

Abstract
This chapter engages with punk and nostalgia and punk’s new role as an important site of cultural heritage by looking at two heritage events: Punk London, a yearlong set of events held at various iconic British venues in 2017, and Punk Rock Bowling, an annual festival of all things punk rock that was held in Las Vegas until 2019. The author argues that citing punk as being “as iconic to the UK’s heritage story as Stonehenge and the British Museum,” as the London event did, is especially peculiar, as the main target of early British punk’s ire was the English monarchy, and many early British punk gestures were intended to undermine hallowed British institutions such as the fashion industry, the BBC, and the monarchy. Both Punk London and Punk Rock Bowling give clear evidence that the heritage discourse has become a key element in generational identity formation, moving it away from imperialist history and closer to mediatized events in the recent past. This chapter also tries to account for some of the disjunctions that a punk retrospective calls to mind, with especial reference to the preservation of punk rock relics, the paradox inherent in fetishizing punk rock memorabilia, and the anomalous experience of seeing live punk performances in a festival setting made by a bunch of elderly punk rock acts—in, of all places, Las Vegas, a city known for exhibiting the worst excesses of capitalism, one of punk rock’s initial targets.
Capabilities, Future Generations, and Climate Justice
Authors: Holland Breena 
Published: February 2022

Abstract
How would a capabilities approach to justice conceive of the relationship between present and future people? The term capabilities refers to conditions or states of enablement that make it possible for people to do things; they are a person’s real opportunities to live a good, or flourishing, human life. In a capabilities approach to intergenerational justice, the relationship between capability thresholds and capability ceilings can provide the basis for setting limits on what people in the present can do to people who will be living in the future. This relationship between capability thresholds and ceilings is applied to consider problems of intergenerational justice raised by a warming global climate. In particular, this chapter addresses how to approach the allocation of emissions reductions needed to prevent dangerous climate change. A capabilities approach sets allowable generational emissions based on what is needed to secure and protect proceeding generations’ capabilities at a threshold level. It entails a sufficientarian commitment to ensuring that each generation inherits an atmosphere that enables a minimum threshold of human capabilities. Securing this threshold also entails a limitarian commitment to establishing upper limits on what some people can do in pursuing a flourishing human life because of how this impacts a global atmosphere that is shared across generations.
Biblical Readings on a Theology of Dao
Authors: Kim Heup Young 
Published: February 2022

Abstract
This chapter highlights that the do (dao/tao, the way), a crucial and common concept in East Asian thought (Confucianism, Daoism, and Buddhism), is a more appropriate interpretative lens for Koreans and East Asians to read the Bible than that of the historically dominant logos of Christian theology. It is useful not only for contextual theology but also for autogenous Korean Christian thought. Further, the do is biblically more appropriate than logos as the root metaphor. Jesus never identified himself as the logos but rather as the hodos, a homologous term to the do. The hermeneutical key of do (dao), which means the unity of knowing and acting, overcomes a dilemma in Western theology, namely, the dichotomy between the conventional theo-logos and the liberational theo-praxis. Here, from the third perspective of theo-dao, the Bible may be read from the interpretative metaphor of do.
Music for Shakespeare in Nineteenth-Century American Theatre
Authors: Pisani Michael V. , Cooke Mervyn 
Published: February 2022

Abstract
On the American stage, especially in the first half of the nineteenth century, performances of Shakespeare were closely allied with British practices since so many actors emigrated from Britain or toured in the United States. This tendency was also reflected in the musical provision for American productions of the Bard’s plays. The gradual development away from British-inspired scoring practices is surveyed in this chapter, which draws on evidence from six distinct sources: (1) individual songs or composers identified on theatrical playbills; (2) references to music in secondary sources such as books and scholarly articles; (3) promptbooks used in productions; (4) instrumental and/or vocal parts (typically in manuscript) found in libraries, mostly in theatre collections; (5) notices of music in primary sources such as reviews or autobiographies; and (6) printed music. The chapter covers music for the professional stage (notably at Daly’s Theatre in New York City, and melodramatic treatments of Macbeth), lower-budget touring and amateur productions, and the highly popular burlesque. The last of these, more than any other stage genre, transformed the Bard’s work into a middlebrow form of entertainment uniquely American in the diversity of the cultural and musical influences it embodied.
