The nuclear and integrated far-infrared emission of nearby Seyfert galaxies
Esquej, P.; Hernán-Caballero, A.; Acosta-Pulido, J. A. +11 more
We present far-infrared (FIR) 70-500 µm imaging observations obtained with Herschel/Photodetector Array Camera (PACS) and Spectral and Photometric Imaging REceiver (SPIRE) of 33 nearby (median distance of 30 Mpc) Seyfert galaxies from the Revised Shapley-Ames (RSA) catalogue. We obtain the FIR nuclear (r = 1 kpc and r = 2 kpc) and integrated…
New identification of the mixed-morphology supernova remnant G298.6-0.0 with possible gamma-ray association
Petre, Robert; Terada, Yukikatsu; Bamba, Aya +4 more
We present an X-ray analysis on the Galactic supernova remnant (SNR) G298.6-0.0 observed with Suzaku. The X-ray image shows a center-filled structure inside a radio shell, implying that this SNR can be categorized as a mixed-morphology (MM) SNR. The spectrum is well reproduced by a single-temperature plasma model in ionization equilibrium, with a …
Evidence for a binary origin of a central compact object
Klochkov, Dmitry; Kavanagh, Patrick; Doroshenko, Victor +3 more
Central compact objects (CCOs) are thought to be young thermally emitting isolated neutron stars that were born during the preceding core-collapse supernova explosion. Here, we present evidence that at least in one case the CCO could have been formed within a binary system. We show that the highly reddened optical source IRAS 17287-3443, located 2…
Star Cluster Formation and Destruction in the Merging Galaxy NGC 3256
Whitmore, B. C.; Chandar, R.; Mulia, A. J.
We use the Advanced Camera for Surveys on the Hubble Space Telescope to study the rich population of young massive star clusters in the main body of NGC 3256, a merging pair of galaxies with a high star formation rate (SFR) and SFR per unit area (ΣSFR). These clusters have luminosity and mass functions that follow power laws, dN/dL ∝ L …
Radiative and mechanical feedback into the molecular gas in the Large Magellanic Cloud. I. N159W
Lebouteiller, V.; Madden, S. C.; Galliano, F. +25 more
We present Herschel SPIRE Fourier Transform Spectrometer (FTS) observations of N159W, an active star-forming region in the Large Magellanic Cloud (LMC). In our observations, a number of far-infrared cooling lines, including carbon monoxide (CO) J = 4 → 3 to J = 12 → 11, [CI] 609 µm and 370 µm, and [NII] 205 µm, are clearly detect…
Measure the distance and extinction for stars in LAMOST survey with Bayesian method
Shi, Jianrong; Zhang, Yong; Wu, Yue +7 more
Using a Bayesian technique, which combines both photometric and spectral information, as well as prior knowledge on the Milky Way, we measured the distance and extinction for about one million stars in the first data release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. Simulations have been performed based on t…
On the Nature of the Enigmatic Object IRAS 19312+1950: A Rare Phase of Massive Star Formation?
Justtanont, K.; Tielens, A. G. G. M.; Boogert, A. C. A. +7 more
IRAS 19312+1950 is a peculiar object that has eluded firm characterization since its discovery, with combined maser properties similar to an evolved star and a young stellar object (YSO). To help determine its true nature, we obtained infrared spectra of IRAS 19312+1950 in the range 5-550 µm using the Herschel and Spitzer space observatories…
Cassini observations of Saturn's southern polar cusp
Coates, A. J.; Krupp, N.; Russell, C. T. +15 more
The magnetospheric cusps are important sites of the coupling of a magnetosphere with the solar wind. The combination of both ground- and space-based observations at Earth has enabled considerable progress to be made in understanding the terrestrial cusp and its role in the coupling of the magnetosphere to the solar wind via the polar magnetosphere…
Unbeamed tidal disruption events at hard X-rays
Walter, R.; Hryniewicz, K.
Context. Owing to their thermal emission, tidal disruption events (TDEs) were regularly detected in the soft X-rays and sometimes in the optical. Only a few TDEs have been detected at hard X-rays: two are high redshift beamed events, one of which occurred at the core of a nearby galaxy, and the most recent one is of a different nature, involving a…
The Compact Star-forming Complex at the Heart of NGC 253
Davidge, T. J.
We discuss integral field spectra of the compact star-forming complex that is the brightest near-infrared (NIR) source in the central regions of the starburst galaxy NGC 253. The spectra cover the H and K passbands and were recorded with the Gemini NIR Spectrograph during subarcsecond seeing conditions. Absorption features in the spectrum of the s…
