The 2022 component separation course will be held in Oslo and online  from 22 August - 2 September

Three new papers has been accepted for publication from RoCS - Rosseland Centre for Solar Physics. Postdoctoral Fellow Avijeet Prasad, Postdoctoral Fellow Nancy Narang and guest researcher Jayant Joshi present their latest findings.

Three teams of scientists from Norway, Czech Republic and Iceland join expertises in the attempt to shed light onto the nature of the most abundant ingredient in the Universe: dark matter.

The second Cosmoglobe workshop will be held digitally from May 2–6.

The image taken by the spacecraft Solar Orbiter 15th of February is the largest solar prominence eruption ever observed in a single image together with the full solar disc. It extended millions of kilometres into space.   

Three publications have been accepted for publication from RoCS autumn 2021 - early winter 2022 . Doctoral Research Fellow Helle Bakke, masterstudent Bruce Chappell and guest researcher Vasco Manuel de Jorge Henriques present their latest findings.

Finally it's settled! NASA and RoCS - Rosseland Centre for Solar Physics will work on a new solar project to better understand the Earth-Sun environment.

Properly characterizing Galactic emission is vital to the future of Cosmic Microwave Background (CMB) science. Though synchrotron and thermal dust emission usually take front stage in polarization, anomalous microwave emission (AME) certainly cannot be discounted as a potential contaminant. Such an assumption could complicate future and current CMB studies. A preprint of this work can be found here.

For the second time in its mission so far, the ESA/NASA Solar Orbiter spacecraft has flown through the tail of a comet. A mission that includes RoCS - Rosseland Centre for Solar Physics.

- We have found the largest resonant oscillations detected in an intense sunspot, says Dr. Shahin Jafarzadeh, guest researcher at RoCS and part of the WaLSA international team behind the research. The results were published 25th of January in Nature Communications.

Today sees the publication of a wealth of results from the spacecraft’s cruise phase. That's not bad for a mission yet to have entered its main science phase. RoCS - Rosseland Centre for Solar Physics is part of the mission.

The flyby on 27 November went well and placed Solar Orbiter onto the correct orbit for its science phase to begin. RoCS - Rosseland Centre for Solar Physics, UiO, takes part in the mission. 

Four publications have been accepted for publication from RoCS in October. Researcher Henrik Eklund and Postdoctoral Fellows Ana Belén Griñón Marin and Atul Mohan present their latest findings.

Two publications have been accepted for publication from RoCS in August. Doctoral Research Fellow Souvik Bose and Guest Researcher Daniel Nóbrega Siverio present their latest findings.

Space mission Solar Orbiter’s SoloHI instrument captures its first coronal mass ejection, which are important drivers of space weather. RoCS – Rosseland Centre for Solar Physics, UiO contributes in the space mission that makes it possible.

Bart De Pontieu, Professor II, explores the findings, advances made, challenges and future hopes for the data collected by IRIS, the NASA Small Explorer spacecraft.

Two publications have been accepted for publication from RoCS in February. Postdoctoral fellows Ana Belén Griñón Marin and Atul Mohan present their latest findings.

A nice start of the year: Four publications have been accepted for publication from RoCS in January. See the overview here.

The spacecraft Solar Orbiter has captured three of the four rocky planets  on video on it’s way to getting closer to the sun. Doctoral Research Fellow Aditi Bhatnagar at RoCS, UiO tells us more about it.

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.
