Existing (Spitzer Space Telescope) and upcoming (Herschel Space Telescope) facilities are deepening our understanding of the role of dust in tracing the energy budget and chemical evolution of galaxie...
New Panoramic View of $^{12}$CO and 1.1 mm Continuum Emission in the Orion A Giant Molecular Cloud. I. Survey Overview and Possible External Triggers of Star Formation
star formation
2014/12/22
We present new, wide, and deep images in the 1.1 mm continuum and the CO ( 1–0) emission toward the northern part of the Orion A Giant Molecular Cloud (Orion-A GMC). The 1.1 mm data were taken with th...
The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
The beaming of external Compton emission
galaxies active radiation mechanisms nonthermal gamma rays theory
2011/10/21
We consider a relativistically moving blob consisting of an isotropic electron distribution that Compton-scatters photons from an external isotropic radiation field. We compute the resulting beaming p...
The final parsec problem: aligning a binary with an external accretion disc
accretion accretion discs – black hole physics – galaxies evolution – stars formation – planets and satellites: formation
2011/10/21
We consider the interaction between a binary system (e.g. two supermassive black holes or two stars) and an external accretion disc with misaligned angular momentum. This situation occurs in galaxy me...
I review the characteristics of cluster populations in other galaxies, with particular emphasis on young star clusters and a comparison with the (known) open cluster population of the Milky Way. Young...
The propagation of relativistic jets in external media
propagation relativistic jets external media
2011/9/29
Relativistic jets are ubiquitous in astrophysical systems that contain compact objects. They transport large amounts of energy to large distances from the source, and their interaction with the ambien...
New Panoramic View of $^{12}$CO and 1.1 mm Continuum Emission in the Orion A Molecular Cloud. I. Survey Overview and Possible External Triggers of Star Formation
Galaxy Astrophysics (astro-ph.GA)
2011/1/6
We present new, wide and deep images in the 1.1 mm continuum and the $^{12}$CO ($J$=1-0) emission toward the northern part of the Orion A Giant Molecular Cloud (Orion-A GMC). The 1.1 mm data were take...
External field effect of modified Newtonian dynamics in the Solar system
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/27
The Modified Newtonian Dynamics (MOND) has been formulated as a modification of the Poisson equation for the Newtonian gravitational field.
Delensing CMB Polarization with External Datasets
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/22
One of the primary scientific targets of current and future CMB polarization experiments is the search for a stochastic background of gravity waves in the early universe. As instrumental sensitivity i...
Interaction of plasma cloud with external electric field in lower ionosphere
plasma cloud lower ionosphere
2017/3/22
In the auroral lower-E and upper-D region of the
ionosphere, plasma clouds, such as sporadic-E layers and
meteor plasma trails, occur daily. Large-scale electric fields,
created by the magnetospher...
