The X-ray outburst of the Galactic Centre magnetar SGR J1745−2900 during the first 1.5 year

In 2013 April a new magnetar, SGR 1745−2900, was discovered as it entered an outburst, at only 2.4 arcsec angular distance from the supermassive black hole at the centre of the Milky Way, Sagittarius A*. SGR 1745−2900 has a surface dipolar magnetic field of ∼2 × 1014 G, and it is the neutron star closest to a black hole ever observed. The new source was detected both in the radio and X-ray bands, with a peak X-ray luminosity LX ∼ 5 × 1035 erg s−1. Here we report on the long-term Chandra (25 observations) and XMM–Newton (eight observations) X-ray monitoring campaign of SGR 1745−2900 from the onset of the outburst in 2013 April until 2014 September. This unprecedented data set allows us to refine the timing properties of the source, as well as to study the outburst spectral evolution as a function of time and rotational phase. Our timing analysis confirms the increase in the spin period derivative by a factor of ∼2 around 2013 June, and reveals that a further increase occurred between 2013 October 30 and 2014 February 21. We find that the period derivative changed from 6.6 × 10−12 to 3.3 × 10−11 s s−1 in 1.5 yr. On the other hand, this magnetar shows a slow flux decay compared to other magnetars and a rather inefficient surface cooling. In particular, starquake-induced crustal cooling models alone have difficulty in explaining the high luminosity of the source for the first ∼200 d of its outburst, and additional heating of the star surface from currents flowing in a twisted magnetic bundle is probably playing an important role in the outburst evolution.

Poems copied by James Diman, ca. 1730-1733

Small pamphlet-sized notebook containing handwritten transcriptions of three poems copied by James Diman, likely in the early 1730s. The notebook contains "The Catholic Remedy. to ye Tune of To all you Ladies, not at land &c.," "Father Ab--y's Will. Col. Sweeper Camb: Dec. 1731," and "The Poet's Lamentation for ye Loss of his cat, w'ch he used to call his Muse" copied from the London Magazine, November 1733. The "Catholic Remedy" begins "You Peope who desire to mend / your Desperate Estate..." and includes the note, "Made upon A--D--'s goving over to take orders. The note refers to the voyage of Addington Davenport (Harvard AB 1719) to England join the priesthood of the Church of England in 1730. "Father Ab--y's Will" begins "To my dear Wife, / My joy and Life..." and was a humorous poem published in 1731 after the death of Harvard College Sweeper Matthew Abdy, and attributed to Jonathan Seccombe (Harvard AB 1728). The "Poet's Lamentation" begins "Oppress'd with Grief, in heavy strains I mourn..." and was written by Joseph Green (Harvard AB 1726) as a parody of a psalm composed by Mather Byles (Harvard AB 1725). Pages 10-12, holding part of "Father Ab--y's Will" are missing, and pages 13-15 are no longer attached to the item.

Student notebook of John Tufts, 1705

Small vellum-covered notebook containing handwritten transcriptions copied by Harvard undergraduate John Tufts from two Harvard textbooks. The notebook is divided into two sections with the first, numbered 1-100, containing an English transcription of "Compendium of Logick" compiled by William Brattle, and the second, numbered 1-66, containing an untitled Latin transcription of Charles Morton's "Compendium Physicae." The flyleaf is inscribed "John Tufts His Book 1705."

Artisans, génies et vedettes : le statut des compositeurs dans la presse musicale française

Ce mémoire propose d’explorer quel(s) statut(s) sont accordés aux compositeurs contemporains dans le contexte musical parisien des premières années du XXe siècle à travers une analyse de la presse musicale spécialisée de l’époque. Le corpus de notre recherche est constitué de trois revues, chacune ancrée dans des sphères de sociabilités bien distinctes : La Revue musicale (histoire et critique), une « revue savante » proche du milieu de la Schola cantorum ; Le Mercure musical, une « petite revue » d’avant-garde militant en faveur de la musique de Maurice Ravel ; et Musica, une « grande revue » destinée à un lectorat issu de la petite bourgeoisie en plein essor, essentiellement féminin et pratiquant la musique en amateur. Cette étude révèle que la traditionnelle opposition entre la conception du compositeur-artisan et celle du compositeur-génie issue de la fin du XVIIIe siècle et du XIXe siècle voit apparaître un troisième joueur à l’aube du XXe siècle : le compositeur-vedette, un statut qui était jusqu’alors généralement réservé aux interprètes. Ces trois statuts coexistent dans le panorama de la presse musicale du tournant du XXe siècle, et leur promotion par certains organes de presse spécifiques répond à une logique tantôt esthétique, tantôt économique. Il se dégage de cette étude que la presse musicale constitue non seulement un indice des variations qu’a subies la figure du compositeur dans le spectre de la grandeur en culture, mais qu’elle a également joué un rôle actif dans ces transformations.
