Improved Cosmological Constraints from New, Old and Combined Supernova Datasets
M. Kowalski, D. Rubin, G. Aldering +67
We present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compi…
A new young stellar cluster embedded in a molecular cloud in the far outer Galaxy
Joao L. Yun, Ana Lopez-Sepulcre, Jose M. Torrelles
We report the discovery of a new young stellar cluster and molecular cloud located in the far outer Galaxy, seen towards IRAS 06361-0142, and we characterise their properties. Near…
A "diamond-ring" star: the unusual morphologic structure of a young (multiple?) object
Joao L. Yun, Jose M. Torrelles, Nuno C. Santos
We have observed IRAS06468-0325 obtaining optical and infrared images through IJHKs and L' filters, K-band low-resolution spectroscopy, together with millimetre line observations o…
Pre-main sequence stars in open clusters. I. The DAY-I catalogue
A. J. Delgado, E. J. Alfaro, J. L. Yun
We present the project we are carrying out at present, the search for and characterisation of pre-main sequence (PMS) stars among the members of Galactic young clusters. The observ…
Multiwavelength analysis of the young open cluster NGC 2362
A. J. Delgado, O. Gonzalez-Martin, E. J. Alfaro +1
We present a multiwavelength analysis of the young open cluster NGC 2362. UBVRcIc CCD photometric observations, together with available data in the Chandra data base, near infrared…
VLT/ISAAC H-band spectroscopy of embedded massive YSOs
T. R. Kendall, W. J. de Wit, J. L. Yun
We have performed intermediate resolution (R = 5000), high signal-to-noise H-band spectroscopy of a small, initial sample of three massive embedded young stellar objects (YSOs), us…
