The Kepler Space Telescope observed thousands of RR Lyrae stars in the K2 mission. In this paper, we present our photometric solutions using extended apertures...
Extended Broad Balmer Emission in the Seyfert 1 Galaxy Markarian 509
We present two-dimensional spectroscopic observations of the circumnuclear region of Mrk 509. The spectra show extended (off-nuclear) broad Balmer emission (...
Extended Hα over compact far-infrared continuum in dusty submillimeter galaxies. Insights into dust distributions and star-formation rates at z ∼ 2
By using data from the Atacama Large Millimeter/submillimeter Array and near-infrared (NIR) integral field spectrographs, including both Spectrograph for...
Extended Main-sequence Turnoffs in the Double Cluster h and χ Persei: The Complex Role of Stellar Rotation
Using Gaia Data Release 2 photometry, we report the detection of extended main-sequence turnoff (eMSTO) regions in the color–magnitude diagrams (CMDs) of the...
Extended nonnuclear infrared emission from Seyfert galaxies
The IRAS observations of well-known Seyfert galaxies have been studied in comparison with previously published ultraviolet and mid-infrared data. The mid- and...
Extended soft X-ray emission in 3CR radio galaxies at z < 0.3: high excitation and broad line galaxies
We analyze Chandra observations of diffuse soft X-ray emission associated with a complete sample of 3CR radio galaxies at z 0.3. We focus on the properties of...
Extended warm gas in the ULIRG Mrk273: Galactic outflows and tidal debris
We present new HST/ACS medium- and narrow-band images and optical Isaac Newton Telescope long-slit spectra of the merging system Mrk273. The HST observations...
Extended wings of the UV SI IV, C IV resonance doublets and the complex [Fe II] profiles in P Cygni.
We investigate the formation and the nature of the extended wings of the UV resonance lines of Si IV 1394, 1402A and C IV 1548 and 1550A in the spectrum of the...
Extended X-Ray Emission around FR II Radio Galaxies: Hot Spots, Lobes, and Galaxy Clusters
We present a systematic analysis of the extended X-ray emission discovered around 35 FR II radio galaxies from the revised Third Cambridge Catalog (3CR) Chandra...
