Halo Concentrations and the Fundamental Plane of Galaxy Clusters
Yutaka Fujita, Megan Donahue, Stefano Ettori +6
According to the standard cold dark matter (CDM) cosmology, the structure of dark halos including those of galaxy clusters reflects their mass accretion history. Older clusters ten…
HST FUV spectroscopy of the short orbital period recurrent nova CI Aql: Implications for white dwarf mass evolution
Edward M. Sion, R. E. Wilson, Patrick Godon +3
An HST COS Far UV spectrum (1170 A to 1800 A) was obtained for the short orbital period recurrent novae (T Pyxidis subclass), CI Aquilae. CI Aql is the only classical CV known to h…
A homogeneous analysis of globular clusters from the APOGEE survey with the BACCHUS code. I. The Northern clusters
T. Masseron, D. A. García-Hernández, Sz. Mészáros +12
We analyze a large sample of 885 GCs giants from the APOGEE survey. We used the Cannon results to separate the red giant branch and the asymptotic giant branch stars, not only allo…
Quantifying the suppression of the (un)-obscured star formation in galaxy cluster cores at 0.20.9
L. Rodríguez-Muñoz, G. Rodighiero, C. Mancini +21
We quantify the star formation (SF) in the inner cores (/0.3) of 24 massive galaxy clusters at 0.20.9 observed by the …
SOFIA/FORCAST resolves 30 - 40 um extended dust emission in nearby active galactic nuclei
Lindsay Fuller, Enrique Lopez-Rodriguez, Chris Packham +7
We present arcsecond-scale observations of the active galactic nuclei (AGNs) of seven nearby Seyfert galaxies observed from the Stratospheric Observatory For Infrared Astronomy (SO…
SPHERE dynamical and spectroscopic characterization of HD142527B
R. Claudi, A. -L. Maire, D. Mesa +50
We detect the accreting low-mass companion HD142527B at a separation of 73 mas (11.4 au) from the star. No other companions with mass greater than 10 MJ are visible in the field of…
