Supernova caught in the act by Palomar Transient Factory
Supernova caught in the act Palomar Transient Factory
2014/6/12
Supernovae—stellar explosions—are incredibly energetic, dynamic events. It is easy to imagine that they are uncommon, but the universe is a big place and supernovae are actually fairly routine. The pr...
Detailed Chemical Abundances of Four Stars in the Unusual Globular Cluster, Palomar 1
Detailed Chemical Abundance Unusual Globular Cluster Palomar
2011/10/17
Detailed chemical abundances for twenty one elements are presented for four red giants in the anomalous outer halo globular cluster Palomar 1 ($R_{\rm{GC}} = 17.2$ kpc, $Z=3.6$ kpc) using high-resolut...
The non-segregated population of blue straggler stars in the remote globular cluster Palomar 14
non-segregated population straggler stars remote globular cluster
2011/9/27
We used deep wide-field observations obtained with the Canada-France-Hawaii Telescope to study the blue straggler star (BSS) population in the innermost five arcminutes of the remote Galactic globular...
Discovery of tidal tails around the distant globular cluster Palomar 14
tidal tails the distant globular cluster Palomar 14
2011/1/13
We report the detection of a pair of degree-long tidal tails associated with the globular cluster Palomar 14, using images obtained at the CFHT. We reveal a power-law departure from a King profile at...
Is Palomar 1 really associated with the Canis Major overdensity?
Palomar Canis Major overdensity
2010/11/16
t has recently been suggested that the peculiar cluster Pal 1 is associated to the Canis Major dwarf galaxy, which existence is still at the center of a debate. Our rst measurement of the cluster's c...
High Resolution HDS/SUBARU chemical abundances of the young stellar cluster Palomar 1

2010/11/9
Context. Palomar 1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered in the Milky Way (MW),...
Direct N-body simulations of globular clusters: (I) Palomar 14
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
We present the first ever direct $N$-body computations of an old Milky Way globular cluster over its entire life time on a star-by-star basis. Using recent GPU hardware at Bonn University, we have per...
