Discovery of a nebula associated with a high proper motion sdB star
R. Ortiz, F. Bijarchian, M. A. Guerrero +2
All B-type subdwarf stars (hereafter sdB) should have low flux of ionizing photons, making them incapable of producing a noticeable circumstellar photoionized shell. However, a few…
The explosive growth of the Messier 74 galaxy. A galaxy doubling its size in less than a Gigayear
Ignacio Ruiz Cejudo, Ignacio Trujillo, Sergio Guerra Arencibia +3
Galaxy formation models predict that galaxies grow inside-out, becoming larger over time. While observations broadly support this paradigm, the nature and timescales of this growth…
Recurrence of the blue wing enhancements in the high ionization lines of SDSS 1004+4112 A
P. Gomez-Alvarez, E. Mediavilla, J. A. Munoz +5
We present integral field spectroscopic observations of the quadruple-lensed QSO SDSS 1004+4112 taken with the fiber system INTEGRAL at the William Herschel Telescope on 2004 Janua…
Extended CIII]lambda1909 emission in Q0957+561
E. Mediavilla, V. Motta, ; S. Arribas +7
2D spectroscopy of Q0957+561 in the CIII]lambda1909 emission line reveals a rich variety of spatially extended features. We point out: (i) a blueshifted region apparently connectin…
