A consistent explanation for the unusual initial mass function and star formation rate in the Central Molecular Zone (CMZ)
Gilles Chabrier, Pierre Dumond
We examine various physical processes that may explain the shallow high-mass slope of the IMF as well as the low SFR in star-forming molecular clouds (MCs) in the Central Molecular…
Universal gravity-driven isothermal turbulence cascade in disk galaxies
Jérémy Fensch, Frédéric Bournaud, Noé Brucy +3
While interstellar gas is known to be supersonically turbulent, the injection processes of this turbulence are still unclear. Many studies suggest a dominant role of gravitational…
Evidence of a Bottom-heavy Initial Mass Function in Massive Early-type Galaxies from Near-infrared Metal Lines
David J. Lagattuta, Jeremy R. Mould, Duncan A. Forbes +3
We present new evidence for a variable stellar initial mass function (IMF) in massive early-type galaxies, using high-resolution, near-infrared spectroscopy from the Folded-port In…
Spectroscopic detections of CIII]1909 at z~6-7: A new probe of early star forming galaxies and cosmic reionisation
Daniel P. Stark, Johan Richard, Stephane Charlot +7
Deep spectroscopic observations of z~6.5 galaxies have revealed a marked decline with increasing redshift in the detectability of Lyman-alpha emission. While this may offer valuabl…
