The Origins of [C II] Emission in Local Star-forming Galaxies
Boquien, M.; Rigopoulou, D.; Armus, L. +17 more
The [C II] 158 µm fine-structure line is the brightest emission line observed in local star-forming galaxies. As a major coolant of the gas-phase interstellar medium, [C II] balances the heating, including that due to far-ultraviolet photons, which heat the gas via the photoelectric effect. However, the origin of [C II] emission remains uncl…
A Herschel Space Observatory Spectral Line Survey of Local Luminous Infrared Galaxies from 194 to 671 Microns
Gao, Yu; Díaz-Santos, Tanio; Lu, Nanyao +18 more
We describe a Herschel Space Observatory 194-671 µm spectroscopic survey of a sample of 121 local luminous infrared galaxies and report the fluxes of the CO J to J-1 rotational transitions for 4≤slant J≤slant 13, the [N II] 205 µm line, the [C I] lines at 609 and 370 µm, as well as additional and usually fainter lines. The CO spe…
The Complete Infrared View of Active Galactic Nuclei from the 70 Month Swift/BAT Catalog
Ueda, Yoshihiro; Kawamuro, Taiki; Ricci, Claudio +5 more
We systematically investigate the near- to far-infrared (FIR) photometric properties of a nearly complete sample of local active galactic nuclei (AGNs) detected in the Swift/Burst Alert Telescope (BAT) all-sky ultra-hard X-ray (14-195 keV) survey. Out of 606 non-blazar AGNs in the Swift/BAT 70 month catalog at high galactic latitudes of | b| > …
ATLASGAL-selected massive clumps in the inner Galaxy. III. Dust continuum characterization of an evolutionary sample
König, C.; Menten, K. M.; Csengeri, T. +8 more
Context. Massive-star formation and the processes involved are still poorly understood. The ATLASGAL survey provides an ideal basis for detailed studies of large numbers of massive-star forming clumps covering the whole range of evolutionary stages. The ATLASGAL Top100 is a sample of clumps selected by their infrared and radio properties to be rep…
The Evolution of the Tully-Fisher Relation between z ∼ 2.3 and z ∼ 0.9 with KMOS3D
Lutz, D.; Wuyts, S.; Förster Schreiber, N. M. +24 more
We investigate the stellar mass and baryonic mass Tully-Fisher relations (TFRs) of massive star-forming disk galaxies at redshift z∼ 2.3 and z∼ 0.9 as part of the {{KMOS}}3{{D}} integral field spectroscopy survey. Our spatially resolved data allow reliable modeling of individual galaxies, including the effect of pressure support on the …
Maximum a posteriori CMB lensing reconstruction
Carron, Julien; Lewis, Antony
Gravitational lensing of the cosmic microwave background (CMB) is a valuable cosmological signal that correlates to tracers of large-scale structure and acts as a important source of confusion for primordial B -mode polarization. State-of-the-art lensing reconstruction analyses use quadratic estimators, which are easily applicable to data. However…
Constraints on Axion-like Particles from X-Ray Observations of NGC1275
Berg, Marcus; Conlon, Joseph P.; Day, Francesca +4 more
Axion-like particles (ALPs) can induce localized oscillatory modulations in the spectra of photon sources passing through astrophysical magnetic fields. Ultra-deep Chandra observations of the Perseus cluster contain over 5× {10}5 counts from the active galactic nucleus (AGN) of the central cluster galaxy NGC1275 and represent a data set…
The X-ray properties of z 6 luminous quasars
Brandt, W. N.; Moretti, A.; Vignali, C. +2 more
We present a systematic analysis of X-ray archival data of all the 29 quasars (QSOs) at z> 5.5 observed so far with Chandra, XMM-Newton and Swift-XRT, including the most-distant quasar ever discovered, ULAS J1120+0641 (z = 7.08). This study allows us to place constraints on the mean spectral properties of the primordial population of luminous T…
The Tip of the Red Giant Branch Distances to Type Ia Supernova Host Galaxies. IV. Color Dependence and Zero-point Calibration
Lee, Myung Gyoon; Jang, In Sung
We present a revised Tip of the Red Giant Branch (TRGB) calibration, accurate to 2.7% of distance. A modified TRGB magnitude corrected for its color dependence, the QT magnitude, is introduced for better measurement of the TRGB. We determine the color-magnitude relation of the TRGB from photometry of deep images of HST/ACS fields around eight near…
DYNAMO-HST survey: clumps in nearby massive turbulent discs and the effects of clump clustering on kiloparsec scale measurements of clumps
Glazebrook, Karl; Obreschkow, Danail; Abraham, Roberto G. +6 more
We present ∼100 pc resolution Hubble Space Telescope Hα images of 10 galaxies from the DYnamics of Newly-Assembled Massive Objects (DYNAMO) survey of low-z turbulent disc galaxies, and use these to undertake the first detailed systematic study of the effects of resolution and clump clustering on observations of clumps in turbulent discs. In the DY…
