X-ray timing analysis of the quasar PG 1211+143
Andrew Lobban, Simon Vaughan, Ken Pounds +1
We report on a timing analysis of a new ~630ks XMM-Newton observation of the quasar, PG 1211+143. We find a well-defined X-ray power spectrum with a well-detected bend at ~7e-5 Hz,…
Probing the Local Bubble with Diffuse Interstellar Bands (DIBs)
Jacco Th. van Loon, Amin Farhang, Atefeh Javadi +2
The Sun lies in the middle of an enormous cavity of a million degree gas, known as the Local Bubble. The Local Bubble is surrounded by a wall of denser neutral and ionized gas. The…
The VMC survey - XVII. The proper motion of the Small Magellanic Cloud and of the Milky Way globular cluster 47 Tucanae
Maria-Rosa L. Cioni, Kenji Bekki, Leo Girardi +8
In this study we use multi-epoch near-infrared observations from the VISTA survey of the Magellanic Cloud system (VMC) to measure the proper motion of different stellar populations…
New quasars behind the Magellanic Clouds. Spectroscopic confirmation of near-infrared selected candidates
Valentin D. Ivanov, Maria-Rosa L. Cioni, Kenji Bekki +7
Quasi--stellar objects (quasars) located behind nearby galaxies provide an excellent absolute reference system for astrometric studies, but they are difficult to identify because o…
Probing the Local Bubble with Diffuse Interstellar Bands. I. Project overview and Southern hemisphere survey
Mandy Bailey, Jacco Th. van Loon, Amin Farhang +4
We have conducted a high signal-to-noise spectroscopic survey of 670 nearby early-type stars, to map Diffuse Interstellar Band (DIB) absorption in and around the Local Bubble. The…
The r-process in Magnetorotational Supernovae
Takuji Tsujimoto, Nobuya Nishimura
One of the hottest open issues involving the evolution of r-process elements is fast enrichment in the early Universe. Clear evidence for the chemical enrichment of r-process eleme…
