The authors obtained near infrared images in J, H, and K filters of the H II region N159 in the LMC with the IR Imager on the 1.5 m telescope of CTIO. Some 50...
IRAS 06562-0337 - Final mass-loss episodes before the formation of a planetary nebula?
The onset of forbidden line emission in the spectrum of a proto-planetary nebula has been detected for the first time in the lapse of only two years. IRAS 06562...
Is star formation a stochastic or a regulated process?
The stellar initial mass function (IMF) is usually assumed to be a probability density distribution function. Recent data appear to question this interpretation...
Dwarf galaxies in the Local Group allow to study in great detail the physical mechanisms responsible for the formation and evolution of galaxies. In fact, their...
J-PLUS: Spectroscopic validation of Hα emission line maps in spatially resolved galaxies
Aims. We present a dedicated automated pipeline to construct spatially resolved emission Hα+[NII] maps and to derive the spectral energy distributions (SEDs) in...
J-PLUS: Uncovering a large population of extreme [OIII] emitters in the local Universe
Context. Over the past decades, several studies have discovered a population of galaxies that undergo very strong star formation events. They are called extreme...
JCMT BISTRO Observations: Magnetic Field Morphology of Bubbles Associated with NGC 6334
We study the HII regions associated with the NGC 6334 molecular cloud observed in the submillimeter and taken as part of the B-fields In STar-forming Region...
JWST/NIRCam Paβ Narrowband Imaging Reveals Ordinary Dust Extinction for Hα Emitters within the Spiderweb Protocluster at z = 2.16
We combine JWST/NIRCam and Subaru/MOIRCS dual Paβ+Hα narrowband imaging to trace the dust attenuation and the star formation activities of a sample of 43 Hα...
Kinematics of the ionized and molecular gas in nearby luminous infrared interacting galaxies
We have observed three luminous infrared galaxy systems which are pairs of interacting galaxies, with the Galaxy Hα Fabry-Perot system mounted on the 4.2 m...
