A history of the Irish novel
\"While some literary critics have traced the origins of the novel back to ancient Greece, the modern novel as an access to the narratives of bourgeois modernity emerged into Western culture in the late seventeenth century. The struggle of that class toward definition and the striving to articulate its character is central to the novel and the stories it tells. Its novelty is found in a formlessness that nonetheless aspires to some idea of order and unity. Indeed, the energies of the early modern novel form can be discerned in its constant assertion of narratives that enact that search for completeness while also allowing for a kind of mourning for the security that older, traditional forms and stories allowed. Thus, novelists, then as now, revel in the possibilities that formal innovation permits while their characters find themselves forced to acknowledge the newness of their world and their experiences in that world\"-- Provided by publisher.

Monitoring AGNs with H\\(\\) Asymmetry. V. Long-term Variation and Evolution of the Broad H\\(\\) Emission-Line Profiles
The physical origins of the diverse emission-line asymmetries observed in the spectra of active galactic nuclei (AGNs) remain incompletely understood. Monitoring the temporal variations of line profiles offers a promising approach to investigating the underlying physics. In this study, we present an analysis of the broad H\\(\\) emission line profiles of eight AGNs observed from the end of 2016 to May 2023 as part of the reverberation mapping campaign titled \"Monitoring AGNs with H\\(\\) Asymmetry\" (MAHA), utilizing data obtained from the Wyoming Infrared Observatory (WIRO) 2.3-meter telescope. We measure the temporal variations of line asymmetry, width, and central velocity shift for the eight objects. Our findings reveal that the variation in asymmetry is positively correlated with H\\(\\) flux in five of the eight objects, while the remaining objects exhibit negative or complex correlations. Furthermore, we observe anti-correlations between line width and H\\(\\) flux for most objects, indicating the presence of the \"breathing\" phenomenon in their H\\(\\) emission lines. In contrast, two objects demonstrate an \"anti-breathing\" phenomenon or complex behavior. We discuss the physical origins of the temporal variations in line profiles and propose the possibility of decomposing the variations in H\\(\\) asymmetry and width into components: one that corresponds to short-term variations in H\\(\\) flux and another that reflects long-term variations in continuum light curves, perhaps driven by radiation pressure.

Challenging us with what we do not know
Jean-Michel Rabaté quotes Friedrich Engels, who claimed that the Irish \"are most internationalistic when they are genuinely nationalistic\". [...]the desire to critique their Irish worlds necessarily means artists critique modernity itself. Essays by Catherine Maignat, Jennifer Way and Neil O'Boyle focus on visual culture, illuminating how images of Ireland become sites of contention, as well as reservoirs of potential meaning at home and abroad. The Reimagining Ireland Reader tells a story of change and transformation, possessing both the comfort of things we know being reimagined, but also challenging us with what we do not know. n Derek Hand is head of the school of English at Dublin City University and author of A History of the Irish Novel (Cambridge University Press)

Monitoring AGNs with H\\(\\beta\\) Asymmetry. IV. First Reverberation Mapping Results of 14 AGNs
We report first-time reverberation mapping results for 14 AGNs from the ongoing Monitoring AGNs with H\\(\\beta\\) Asymmetry campaign (MAHA). These results utilize optical spectra obtained with the Long Slit Spectrograph on the Wyoming Infrared 2.3m Telescope between 2017 November-2023 May. MAHA combines long-duration monitoring with high cadence. We report results from multiple observing seasons for 9 of the 14 objects. These results include H\\(\\beta\\) time lags, supermassive black hole masses, and velocity-resolved time lags. The velocity-resolved lags allow us to investigate the kinematics of the broad-line region.

No Clear, Direct Evidence for Multiple Protoplanets Orbiting LkCa 15: LkCa 15 bcd are Likely Inner Disk Signals
Two studies utilizing sparse aperture masking (SAM) interferometry and \\(H_{\\rm \\alpha}\\) differential imaging have reported multiple jovian companions around the young solar-mass star, LkCa 15 (LkCa 15 bcd): the first claimed direct detection of infant, newly-formed planets (\"protoplanets\"). We present new near-infrared direct imaging/spectroscopy from the SCExAO system coupled with the CHARIS integral field spectrograph and multi-epoch thermal infrared imaging from Keck/NIRC2 of LkCa 15 at high Strehl ratios. These data provide the first direct imaging look at the same wavelengths and in the same locations where previous studies identified the LkCa 15 protoplanets and thus offer the first decisive test of their existence. The data do not reveal these planets. Instead, we resolve extended emission tracing a dust disk with a brightness and location comparable to that claimed for LkCa 15 bcd. Forward-models attributing this signal to orbiting planets are inconsistent with the combined SCExAO/CHARIS and Keck/NIRC2 data. An inner disk provides a more compelling explanation for the SAM detections and perhaps also the claimed \\(H_{\\alpha}\\) detection of LkCa 15 b. We conclude that there is currently no clear, direct evidence for multiple protoplanets orbiting LkCa 15, although the system likely contains at least one unseen jovian companion. To identify jovian companions around LkCa 15 from future observations, the inner disk should be detected and its effect modeled, removed, and shown to be distinguishable from planets. Protoplanet candidates identified from similar systems should likewise be clearly distinguished from disk emission through modeling.
