A family of cometary globules at the periphery of Cyg OB1: the star HBHA 3703-01 and the reflection nebula GM 2-39
Lozinskaya, T. A.; Arkhipova, V. P.; Egorov, O. V. +7 more
The interstellar medium in the region of a family of cometary globules including the reflection nebula GM 2-39 has been analysed based on our observations with a slit spectrograph, the results of our previous observations with a Fabry-Perot interferometer in the Hα line and Spitzer archival data (Hora et al.), together with CO microwave data (Leun…
Investigating the Core Morphology-Seyfert Class Relationship with Hubble Space Telescope Archival Images of Local Seyfert Galaxies
Kim, Hwihyun; Rutkowski, M. J.; Windhorst, R. A. +2 more
The unified model of active galactic nuclei (AGNs) has provided a successful explanation for the observed diversity of AGNs in the local universe. However, recent analysis of multi-wavelength spectral and image data suggests that the unified model is only a partial theory of AGNs, and may need to be augmented to remain consistent with all observat…
Some results on the radio-SZ correlation for galaxy cluster radio halos
Basu, K.
We present correlation results for the radio halo power in galaxy clusters with the integrated thermal Sunyaev-Zel'dovich (SZ) effect signal, including new results obtained at sub-GHz frequencies. The radio data is compiled from several published works, and the SZ measurements are taken from the Planck ESZ cluster catalog. The tight correlation be…
The Sub-surface Structure of a Large Sample of Active Regions
Bogart, R. S.; Basu, S.; Baldner, C. S.
We employ ring-diagram analysis to study the sub-surface thermal structure of active regions. We present results using a large number of active regions over the course of Solar Cycle 23. We present both traditional inversions of ring-diagram frequency differences, with a total sample size of 264, and a statistical study using Principal Component A…
The preferentially magnified active nucleus in IRAS F10214+4724 - I. Lens model and spatially resolved radio emission
Heywood, I.; Serjeant, S.; Deane, R. P. +5 more
This is the first paper in a series that presents a multiwavelength analysis of the archetype ultraluminous infrared galaxy IRAS F10214+4724, a gravitationally lensed, starburst/active galactic nucleus at z = 2.3. Here we present a new lens model and spatially resolved radio data, as well as a deep Hubble Space Telescope (HST) F160W map. The lens …
Dust properties of clumpy disc galaxies at z ∼ 1.3 with Herschel-SPIRE
Glazebrook, Karl; Blake, Chris; Wisnioski, Emily +1 more
We present the far-infrared-derived dust properties from Herschel Spectral and Photometric Imaging Receiver of the WiggleZ kinematic sample of 13 star-forming galaxies at z ∼ 1.3, with existing ancillary ∼kpc resolution integral field spectroscopy. We detect three galaxies individually and place limits on the remainder by stacking. The detected ga…
SDSS J002531.46-104022.2 at z = 0.30: a candidate for the (ultra)luminous infrared galaxy to optical quasar transition
Villar-Martín, M.; Drouart, G.; Emonts, B. +2 more
Using data obtained with the Australia Telescope Compact Array (ATCA), we have characterized the amount, spatial distribution and kinematics of the molecular gas in the merging, double-nucleus type 2 quasar (QSO) SDSS J002531.46-104022.2 (hereafter SDSS J0025-10) at z = 0.30 using the CO(1-0) transition. This is one of the scarce examples of quasa…
Observations of Sy2 galaxy NGC 3281 by XMM-Newton and INTEGRAL satellites
Vasylenko, A. A.; Fedorova, E.; Zhdanov, V. I.
We present the results of the analysis of X-ray properties of the Seyfert 2 galaxy NGC 3281, based on the observational data obtained by XMM-Newton and INTEGRAL within the energy ranges 0.2-12 keV and 20-150 keV, respectively. The XMM-Newton spectrum of this object is presented for the first time. We show that fitting the X-ray spectrum of this ga…
X-ray emission from RX J1720.1+2638 and Abell 267: A comparison between a fossil and a non-fossil system
Jiménez-Bailón, E.; Aguerri, J. A. L.; Lozada-Muñoz, M.
We present the XMM-Newton X-ray analysis of RX J1720.1+2638 and Abell 267, a non-fossil and a fossil system, respectively. The whole spectrum of both objects can be explained by thermal emission. The luminosities found for RX J1720.1+2638 and Abell 267 in the 2-10 keV band are 6.20+0.04-0.02{×}1044 and 3.90+0.…
Attempt to detect the granulation signature in the HgMn star HD 175640 from CoRoT light curves
Alecian, G.; Ghazaryan, S.; Harutyunian, H.
HgMn stars are affected by atomic diffusion processes. Because theoretical models based on atomic diffusion require that the atmospheres of ApBp stars have to be much more stable than those of normal stars, the detection or the absence of detection of granulation in them should be an interesting information for the modelling. We would like to addr…
