Hot WHIM counterparts of FUV OVI absorbers: Evidence in the line-of-sight towards quasar 3C 273
Jussi Ahoranta, Jukka Nevalainen, Nastasha Wijers +7
We explore the high spectral resolution X-ray data towards the quasar 3C273 to search for signals of hot ( K) X-ray-absorbing gas co-located with two established inte…
Star formation histories of the LEGUS dwarf galaxies (III): the non-bursty nature of 23 star forming dwarf galaxies
M. Cignoni, E. Sacchi, M. Tosi +15
We derive the recent star formation histories of 23 active dwarf galaxies using HST observations from the Legacy Extragalactic UV Survey (LEGUS). We apply a color-magnitude diagram…
Diverse properties of Ly-alpha emission in low-redshift compact star-forming galaxies with extremely high [OIII]/[OII] ratios
Y. I. Izotov, D. Schaerer, G. Worseck +5
We present observations with the Cosmic Origins Spectrograph onboard the Hubble Space Telescope of eight compact star-forming galaxies at redshifts z=0.02811-0.06540, with low oxyg…
The "Red Radio Ring": Ionised and Molecular Gas in a Starburst/Active Galactic Nucleus at
K. C. Harrington, A. Vishwas, A. Weiss +13
We report the detection of the far-infrared (FIR) fine-structure line of singly ionised nitrogen, \Nplusa, within the peak epoch of galaxy assembly, from a strongly lensed galaxy,…
Murchison Widefield Array and XMM-Newton observations of the Galactic supernova remnant G5.9+3.1
D. Onić, M. D. Filipović, I. Bojičić +27
In this paper we discuss the radio continuum and X-ray properties of the so-far poorly studied Galactic supernova remnant (SNR) G5.9+3.1. We present the radio spectral energy distr…
Torus model properties of an ultra-hard X-ray selected sample of Seyfert galaxies
I. García-Bernete, C. Ramos Almeida, A. Alonso-Herrero +15
We characterize for the first time the torus properties of an ultra-hard X-ray (14-195 keV) volume-limited (DL<40 Mpc) sample of 24 Seyfert (Sy) galaxies (BCS40 sample). The sample…
Initial phases of high-mass star formation: A multiwavelength study towards the extended green object G12.42+0.50
Namitha Issac, Anandmayee Tej, Tie Liu +4
We present a multiwavelength study of the extended green object, G12.42+0.50 in this paper. The associated ionized, dust, and molecular components of this source are studied in det…
Young open cluster IC 4996 and its vicinity: multicolor photometry and Gaia DR2 astrometry
V. Straižys, R. P. Boyle, K. Milašius +9
The open cluster IC 4996 in Cygnus and its vicinity are investigated by applying a two-dimensional photometric classification of stars measured in the Vilnius seven-color photometr…
Clocking the assembly of double-barred galaxies with the MUSE TIMER project
A. de Lorenzo-Cáceres, P. Sánchez-Blázquez, J. Méndez-Abreu +11
The formation of two stellar bars within a galaxy has proved challenging for numerical studies. It is yet not clear whether the inner bar is born via a star formation process promo…
