Planck's dusty GEMS. V. Molecular wind and clump stability in a strongly lensed star-forming galaxy at z=2.2
R. Canameras, N. P. H. Nesvadba, M. Limousin +6
We report the discovery of a molecular wind signature from a massive intensely star-forming clump of a few Msun, in the strongly gravitationally lensed submillimeter galaxy…
Coordinated mm/sub-mm observations of Sagittarius A* in May 2007
D. Kunneriath, A. Eckart, S. Vogel +26
At the center of the Milky Way, with a distance of ~8 kpc, the compact source Sagittarius A* (SgrA*) can be associated with a super massive black hole of ~4x10^6 solar masses. SgrA…
Planck's Dusty GEMS. VII. Atomic carbon and molecular gas in dusty starburst galaxies at z=2 to 4
N. Nesvadba, R. Canameras, R. Kneissl +5
The bright [CI] 1-0 and [CI] 2-1 lines of atomic carbon are becoming more and more widely employed tracers of the cold neutral gas in high-redshift galaxies. Here we present observ…
Planck's Dusty GEMS: Gravitationally lensed high-redshift galaxies discovered with the Planck survey
R. Canameras, N. P. H. Nesvadba, D. Guery +30
We present an analysis of 11 bright far-IR/submm sources discovered through a combination of the Planck survey and follow-up Herschel-SPIRE imaging. Each source has a redshift z=2.…
Coordinated multi-wavelength observations of Sgr A*
A. Eckart, R. Schoedel, F. K. Baganoff +26
We report on recent near-infrared (NIR) and X-ray observations of Sagittarius A* (Sgr A*), the electromagnetic manifestation of the ~4x10^6 solar masses super-massive black hole (S…
Planck's dusty GEMS. IV. Star formation and feedback in a maximum starburst at z=3 seen at 60-pc resolution
R. Canameras, N. Nesvadba, R. Kneissl +7
We present an analysis of high-resolution ALMA interferometry of CO(4-3) line emission and dust continuum in the "Ruby" (PLCK_G244.8+54.9), a bright, gravitationally lensed galaxy…
Planck's Dusty GEMS. III. A massive lensing galaxy with a bottom-heavy stellar initial mass function at z=1.5
R. Canameras, N. P. H. Nesvadba, R. Kneissl +8
We study the properties of the foreground galaxy of the Ruby, the brightest gravitationally lensed high-redshift galaxy on the sub-millimeter sky as probed by the Planck satellite,…
Planck's Dusty GEMS. II. Extended [CII] emission and absorption in the Garnet at z=3.4 seen with ALMA
N. Nesvadba, R. Kneissl, R. Canameras +9
We present spatially resolved ALMA [CII] observations of the bright (flux density S=400 mJy at 350 microns), gravitationally lensed, starburst galaxy PLCK G045.1+61.1 at z=3.427, t…
Planck's dusty GEMS. VI. Multi-J CO excitation and interstellar medium conditions in dusty starburst galaxies at z=2-4
R. Canameras, C. Yang, N. P. H. Nesvadba +8
We present an extensive CO emission-line survey of the Planck's dusty GEMS, a small set of 11 strongly lensed dusty star-forming galaxies at z = 2-4 discovered with Planck and Hers…
Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics
The ATLAS Collaboration, G. Aad, E. Abat +2604
A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together w…
An evolving hot spot orbiting around Sgr A*
M. Zamaninasab, A. Eckart, L. Meyer +9
Here we report on recent near-infrared observations of the Sgr A* counterpart associated with the super-massive ~ 4x10^6 M_sun black hole at the Galactic Center. We find that the M…
Planck's Dusty GEMS. VIII. Dense-gas reservoirs in the most active dusty starbursts at z~3
R. Canameras, N. P. H. Nesvadba, R. Kneissl +6
We present ALMA, NOEMA, and IRAM-30m/EMIR observations of the high-density tracer molecules HCN, HCO+, and HNC in three of the brightest lensed dusty star-forming galaxies at z~3-3…
Simultaneous NIR/sub-mm observation of flare emission from SgrA*
