CO(J = 1-0) Imaging of M51 with CARMA and the Nobeyama 45 m Telescope
Patience, Jenny; Scoville, Nick; Koda, Jin +6 more
We report the CO(J = 1-0) observations of the Whirlpool Galaxy M51 using both the Combined Array for Research in Millimeter Astronomy (CARMA) and the Nobeyama 45 m telescope (NRO45). We describe a procedure for the combination of interferometer and single-dish data. In particular, we discuss (1) the joint imaging and deconvolution of heterogeneous…
Supermassive Black Hole Mass Estimates Using Sloan Digital Sky Survey Quasar Spectra at 0.7 < z < 2
Hall, Patrick B.; Rafiee, Alireza
We present Mg II-based black hole (BH) mass estimates for 27,602 quasars with rest-frame UV spectra available in the Sloan Digital Sky Survey Data Release Three. This estimation is possible due to the existence of an empirical correlation between the radius of the broad-line region (BLR) and the continuum luminosity at 3000 Å. We regenerate this c…
Fundamental Parameters, Integrated Red Giant Branch Mass Loss, and Dust Production in the Galactic Globular Cluster 47 Tucanae
van Loon, J. Th.; Hora, J. L.; Zijlstra, A. A. +12 more
Fundamental parameters and time evolution of mass loss are investigated for post-main-sequence stars in the Galactic globular cluster 47 Tucanae (NGC 104). This is accomplished by fitting spectral energy distributions (SEDs) to existing optical and infrared photometry and spectroscopy, to produce a true Hertzsprung-Russell diagram. We confirm the …
The North American and Pelican Nebulae. II. MIPS Observations and Analysis
Stapelfeldt, K. R.; Guieu, S.; Carpenter, J. M. +9 more
We present observations of ~7 deg2 of the North American and Pelican Nebulae region at 24, 70, and 160 µm with the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS). We incorporate the MIPS observations with earlier Spitzer Infrared Array Camera (IRAC) observations, as well as archival near-infrared (IR) and …
The Chandra ACIS Survey of M33 (ChASeM33): The Final Source Catalog
Mazeh, T.; Pietsch, W.; Haberl, F. +16 more
This study presents the final source catalog of the Chandra ACIS Survey of M33 (ChASeM33). With a total exposure time of 1.4 Ms, ChASeM33 covers ~70% of the D 25 isophote (R ≈ 4.0 kpc) of M33 and provides the deepest, most complete, and detailed look at a spiral galaxy in X-rays. The source catalog includes 662 sources, reaches a limiti…
The Magellanic Quasars Survey. I. Doubling the Number of Known Active Galactic Nuclei Behind the Small Magellanic Cloud
Udalski, Andrzej; Kozłowski, Szymon; Kochanek, Christopher S.
We report the spectroscopic confirmation of 29 new, 12 plausible, and three previously known quasars behind the central ~1.5 deg2 region of the Small Magellanic Cloud (SMC). These were identified in a single 2DF/AAOMEGA observation on the Anglo-Australian Telescope of 268 candidates selected primarily based on their mid-IR colors, along…
The M 33 Synoptic Stellar Survey. I. Cepheid Variables
Macri, Lucas M.; Pellerin, Anne
We have conducted a ground-based BVI synoptic survey of the Local Group galaxy M 33 which covers most of its disk and spans a period of 7 years. The survey targets luminous, long-period variables such as Cepheids and Miras and combines images from the DIRECT project and follow-up observations at the WIYN 3.5 m telescope. This paper, the first in a…
Underflight Calibration of SOHO/CDS and Hinode/EIS with EUNIS-07
Del Zanna, Giulio; Young, Peter R.; Brosius, Jeffrey W. +4 more
Flights of Goddard Space Flight Center's Extreme Ultraviolet Normal Incidence Spectrograph (EUNIS) sounding rocket in 2006 and 2007 provided updated radiometric calibrations for Solar and Heliospheric Observatory/Coronal Diagnostic Spectrometer (SOHO/CDS) and Hinode/Extreme Ultraviolet Imaging Spectrometer (Hinode/EIS). EUNIS carried two independe…
Forbidden and Intercombination Lines of RR Telescopii: Wavelength Measurements and Energy Levels
Young, P. R.; Lobel, A.; Feldman, U.
Ultraviolet and visible spectra of the symbiotic nova RR Telescopii are used to derive reference wavelengths for many forbidden and intercombination transitions of ions +1 to +6 of elements C, N, O, Ne, Na, Mg, Al, Si, P, S, Cl, Ar, K, and Ca. The wavelengths are then used to determine new energy values for the levels within the ions' ground confi…
Blazar 3C 454.3 in Outburst and Quiescence during 2005-2007: Two Variable Synchrotron Emission Peaks
Gurwell, Mark A.; Ogle, Patrick M.; Wehrle, Ann E. +1 more
We monitored the flaring blazar 3C 454.3 during 2005 June-July with the Spitzer Infrared Spectrograph (IRS: 15 epochs), Infrared Array Camera (IRAC: 12 epochs), and Multiband Imaging Photometer (MIPS: 2 epochs). We also made Spitzer IRS, IRAC, and MIPS observations from 2006 December to 2007 January when the source was in a low state, the latter s…
