Journal ArticleDOI
Hierarchical Star Formation in Nearby LEGUS Galaxies
Debra Meloy Elmegreen,Bruce G. Elmegreen,Angela Adamo,Angela Adamo,Alessandra Aloisi,Jennifer E. Andrews,Francesca Annibali,Stacey N. Bright,Daniela Calzetti,Michele Cignoni,Aaron S. Evans,Aaron S. Evans,J. S. Gallagher,Dimitrios A. Gouliermis,Dimitrios A. Gouliermis,Eva K. Grebel,Deidre A. Hunter,Kelsey E. Johnson,Hwihyun Kim,Janice C. Lee,Elena Sabbi,Linda J. Smith,David A. Thilker,Monica Tosi,Leonardo Ubeda +24 more
TL;DR: In this article, the authors studied the hierarchical structure of 12 late-type LEGUS galaxies by determining the numbers and fluxes of nested regions as a function of size from 1 to 200 pc.
Journal ArticleDOI
Simulations of XUV Disks with a Star Formation Density Threshold
TL;DR: In this paper, the authors run smooth particle hydrodynamics simulations of disk galaxies with constant-density extended gas disks to test whether overdensities owing to spiral structure in the outer disk can reproduce the observed star formation.
Journal ArticleDOI
An oxygen abundance gradient into the outer disc of M81
Maria T. Patterson,Rene A. M. Walterbos,Robert C. Kennicutt,Cristina Chiappini,David A. Thilker +4 more
TL;DR: In this article, the authors presented an extended Hα imaging of the outer disc of M81 and luminosities for 40 Hii regions out to ∼3.25 R25.
Journal ArticleDOI
SDSS-IV MaNGA : spatially resolved star-formation histories and the connection to galaxy physical properties
Kate Rowlands,Timothy M. Heckman,Vivienne Wild,Nadia L. Zakamska,Vicente Rodriguez-Gomez,Jorge K. Barrera-Ballesteros,Jennifer M. Lotz,Jennifer M. Lotz,David A. Thilker,Brett H. Andrews,Médéric Boquien,Jon Brinkmann,Joel R. Brownstein,Hsiang-Chih Hwang,Rebecca Smethurst +14 more
TL;DR: In this paper, V W acknowledges support from the European Research Council Starting Grant SEDmorph (PI V Wild) and PI V Wild (PI W) starting grant SED morph.
Journal ArticleDOI
Characterizing uniform star formation efficiencies with marginally stable galactic discs
O. Ivy Wong,Gerhardt R. Meurer,Gerhardt R. Meurer,Zheng Zheng,Timothy M. Heckman,David A. Thilker,Martin Zwaan +6 more
TL;DR: In this article, the authors examined the HI-based star formation efficiency (SFE_HI), the ratio of star formation rate to the atomic Hydrogen (HI) mass, in the context of a constant stability star-forming disk model.
