Heating of the solar atmosphere (i.e., the chromosphere, the transition region, and the corona) has been a much-debated topic in solar physics for many decades. Seven researchers and scientists at RoCS - Rosseland Centre for Solar Physics, UiO, comes up with some answers in a worldwide cooperation.
An article in Titan is dedicated a breakthrough work of the WaLSA international working group where Shahin Jafarzadeh from RoCS - Rosseland Centre of Solar Physics, UiO, take part.
Solar Orbiter is getting ready for the first of many gravity assist flybys of Venus on 27 December, to start bringing it closer to the Sun and tilting its orbit in order to observe our star from different perspectives.
This BeyondPlanck paper presents new images of polarized emission from astrophysical sky components using never before combined data sets with a brand new approach.
Instrumental calibration is vital for the results of a CMB experiment to make sense. But how can we calibrate the instrument using measurements that we ideally need to calibrate the instrument to measure properly?
The BeyondPlanck collaboration has performed the most detailed analysis of the Planck Low Frequency Instrument (LFI) data to date, leading to a cleaner view of both the early universe and our own Milky Way.
Map-making of the Cosmic Microwave Background is an essential step that produces colourful 2D maps of the footprint of the early universe. Here cosmologists set the basis for the innovative map-making algorithm employed in BeyondPlanck.
The BeyondPlanck collaboration chases faint signals in the cosmic microwave background (CMB), an echo from the Big Bang, with this novel approach.
Researcher Shahin Jafarzadeh's and PhD candidate Henrik Eklund's articles on the project "ALMA – The key to the Sun’s coronal heating problem" have been accepted for publication.
After summer break six RoCS publications have been accepted for publication. Luc Rouppe van der Voort, Jayant Joshi, Vasco M. J. Henriques, Henrik Eklund, Juan Camillo Guevara Gómez and Lars Frogner have had their articles published or accepted for publication.
This summer, the space probe Solar Orbiter took the closest pictures ever taken of the sun. The images will help researchers understand the sun better. Professor Mats Carlsson at RoCS - Rosseland Center for Solar Physics, UiO, leads the Norwegian research group's work with Solar Orbiter.
The Institute of Theoretical Astrophysics welcomes two new members of cosmology and extragalactic astronomy group. Ismael and Renate will create mocks of cosmological data, and explore alternative cosmological models.
The EU-funded design study of the world's largest sub-millimetre astronomical telescope is about to start. The work, led by the University of Oslo, includes a study to power the telescope by renewable energy.
At the Institute of Theoretical Astrophysics the number of researchers is growing tremendously. Get to know five brilliant astrophysicists, their research, ambitions and stories.
For the first time torsional Alfvén waves have been directly observed in the solar corona by a team of researchers from the University of Oslo and the University of Warwick. The discovery sheds light on the origin of magnetic waves and their role in the heating of the Sun’s outer atmosphere, the corona.
Solar physicists have uncovered how the Sun’s magnetic waves strengthen and grow as they emerge from its surface.
Håkon Dahle (ITA/UiO) and his international team observed straight into the bright and hot heart of a galaxy 11 billion years old in no less than 12 multiple, gravitationally lensed images. The finding casts light onto a crucial era in our universe’s history: the epoch of reionization.
The Japanese Institute of Space and Astronautical Science has chosen for its next strategic mission LiteBIRD, a small space observatory. Six researches of the Institute of Theoretical Astrophysics are involved in the project.
