Spitzer Microlens Measurement of a Massive Remnant in a Well-Separated Binary
Y. Shvartzvald, A. Udalski, A. Gould +63
We report the detection and mass measurement of a binary lens OGLE-2015-BLG-1285La,b, with the more massive component having (80% probability). A main-sequence…
Silicate dust in the environment of RS Ophiuchi following the 2006 eruption
A. Evans, C. E. Woodward, L. A. Helton +20
We present further Spitzer Space Telescope observations of the recurrent nova RS Ophiuchi, obtained over the period 208-430 days after the 2006 eruption. The later Spitzer IRS data…
Infrared observations of the 2006 outburst of the recurrent nova RS Ophiuchi: the early phase
A. Evans, T. Kerr, Bin Yang +20
We present infrared spectroscopy of the recurrent nova RS Ophiuchi, obtained 11.81, 20.75 and 55.71 days following its 2006 eruption. The spectra are dominated by hydrogen recombin…
An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
A. J. Levan, N. R. Tanvir, S. B. Cenko +58
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major…
Metallicity and effective temperature of the secondary of RS Oph
Ya. V. Pavlenko, A. Evans, T. Kerr +6
The recurrent nova RS Oph undergoes nova eruptions every ~ 10-20years as a result of thermonuclear runaway on the surface of a white dwarf close to the Chandrasekhar limit. Both th…
A search for the optical and near-infrared counterpart of the accreting millisecond X-ray pulsar XTE J1751-305
P. G. Jonker, G. Nelemans, Z. Wang +14
We have obtained optical and near-infrared images of the field of the accreting millisecond X-ray pulsar XTE J1751-305. There are no stars in the 0.7'' error circle (0.7'' is the o…
Changes in the red giant and dusty environment of the recurrent nova RS Ophiuchi following the 2006 eruption
M. T. Rushton, B. Kaminsky, D. K. Lynch +8
We present near infrared spectroscopy of the recurrent nova RS Oph obtained on several occasions after its latest outburst in 2006 February. The 1-5 mircon spectra are dominated by…
Spitzer and ground-based infrared observations of the 2006 eruption of RS Ophiuchi
A. Evans, C. E. Woodward, L. A. Helton +18
We present Spitzer Space Telescope and complementary ground-based infrared observations of the recurrent nova RS Ophiuchi, obtained over the period 64-111 days after the 2006 erupt…
Optical and Infrared Spectroscopy of the type IIn SN 1998S : Days 3-127
A. Fassia, W. P. S. Meikle, N. Chugai +14
We present contemporary infrared and optical spectroscopic observations of the type IIn SN 1998S for the period between 3 and 127 days after discovery. In the first week the spectr…
The UKIRT Hemisphere Survey: Definition and J-band Data Release
S. Dye, A. Lawrence, M. A. Read +23
This paper defines the UK Infra-Red Telescope (UKIRT) Hemisphere Survey (UHS) and release of the remaining ~12,700 sq.deg of J-band survey data products. The UHS will provide conti…
A glimpse of the end of the dark ages: the gamma-ray burst of 23 April 2009 at redshift 8.3
N. R. Tanvir, D. B. Fox, A. J. Levan +59
It is thought that the first generations of massive stars in the Universe were an important, and quite possibly dominant, source of the ultra-violet radiation that reionized the hy…
