Journal ArticleDOI

Paul P. Plucinsky,Benjamin F. Williams,Knox S. Long,Terrance J. Gaetz,Manami Sasaki,Wolfgang Pietsch,R. Tullmann,Randall K. Smith,Randall K. Smith,William P. Blair,David J. Helfand,John P. Hughes,P. Frank Winkler,Miguel A. de Avillez,Luciana Bianchi,Dieter Breitschwerdt,Richard J. Edgar,Parviz Ghavamian,Jonathan E. Grindlay,Frank Haberl,Robert P. Kirshner,Kip D. Kuntz,Kip D. Kuntz,Tsevi Mazeh,Thomas G. Pannuti,Avi Shporer,David A. Thilker +26 more
TL;DR: Chandra ACIS Survey of M33 (ChASeM33) as discussed by the authors provides the most intensive, high-resolution assessment of the X-ray source populations available for the confused inner regions of the galaxy.
Journal ArticleDOI
The Universal Initial Mass Function in the Extended Ultraviolet Disk of M83
Jin Koda,Masafumi Yagi,Samuel Boissier,Armando Gil de Paz,Masatoshi Imanishi,Jennifer Donovan Meyer,Barry F. Madore,David A. Thilker +7 more
TL;DR: In this paper, the first complete census of very young stellar clusters over the entire XUV disk was reported, and the standard, but stochastically sampled, initial mass function (IMF) is preferred over the truncated IMF because there are low-mass stellar clusters (10^2-3 M_☉) that host massive O-type stars.
Journal ArticleDOI
Spitzer Observations of Star Formation in the Extreme Outer Disk of M83 (NGC5236)
Hui Dong,Daniela Calzetti,Michael W. Regan,David A. Thilker,Luciana Bianchi,Gerhardt R. Meurer,Fabian Walter +6 more
TL;DR: In this paper, the authors used the Spitzer Infrared Array Camera (IRAC) observations of two fields in the extended UV disk (XUV-disk) of M83 to constrain stellar masses and ages of the UV clumps in the fields.
Journal ArticleDOI
Quantifying non-star-formation-associated 8 μm dust emission in NGC 628
Alison F. Crocker,Daniela Calzetti,David A. Thilker,G. Aniano,Bruce T. Draine,Leslie K. Hunt,Robert C. Kennicutt,Karin Sandstrom,J. D. T. Smith +8 more
TL;DR: In this paper, the authors combined H? and IRAC images of the nearby spiral galaxy NGC?628 and found that between 30% and 43% of its 8?m dust emission is not related to recent star formation.
Journal ArticleDOI
Massive star formation within the Leo 'primordial' ring.
David A. Thilker,Jennifer L. Donovan,David Schiminovich,Luciana Bianchi,Samuel Boissier,Armando Gil de Paz,Barry F. Madore,D. Christopher Martin,Mark Seibert +8 more
TL;DR: The detection of ultraviolet light from gaseous substructures of the Leo ring is reported, implying the onset of a burst of star formation or continuous star formation of moderate (∼108-yr) duration, and it is speculated that the complexes are dwarf galaxies observed during their formation, but distinguished by their lack of a dark matter component.
