Nanoflares are low energy events, difficult to observe due to their low X-ray energies. The European Solar Telescope will help us unveil these fast events.
En par-ustabil supernova er antageligvis en av de kraftigste eksplosjonene vi har i universet, opp til 100 ganger kraftigere enn en type Ia supernovaer. Det var de første stjernene som antageligvis endte sine dager i par-ustabile supernovaer.
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.
What is the difference between an astronomer and an astronaut? Is astronomer and astrophysicist basically the same scientist? And what about astrologer? Let me clear this up and guide you through a bit of astro-history.
“Hei! Jeg heter Helle, og er en doktorgradsstipendiat.” Slik begynner de fleste presentasjonene mine, men av en eller annen grunn slutter jeg aldri å være nervøs før et foredrag. Blir du også nervøs før en presentasjon? Jeg har skrevet ned noen av mine tips til å gjøre opplevelsen litt mindre nervepirrende.
I løpet av en lang prosess kan man noen ganger, om man er heldig, ende opp med litt bonuskunnskap i den andre enden.
Remember what slender Ca II H chromospheric filbrils are? The advanced optics of the future 4-m European Solar Telescope - EST will unveil these small-scale fibrillar structures, the waves they support and their magnetic fields.
If you've ever given up on a dream or if your dreams took you somewhere unexpected, this one's for you.
Corona times are going to have a special place in the future history books! What are we going to tell our kids? We sat at home, watched Netflix, made, saw and laughed at memes to save the world! To be honest, this is not all!
Have you ever felt like you don't belong? That you are "faking it 'til you make it"? Or sometimes even feel like you will never “make it”?
The second annual report of the Rosseland Centre for Solar Physics is out! Here the diary of one year-long achievements of the Centre of Excellence at the University of Oslo studying our life giving star: the Sun.
Quiet Sun magnetic fields are thought to significantly contribute to the energy and heating of the solar atmosphere. The question is: how much?
Jeg er astrofysiker, og tar en doktorgrad i kosmologi. Bare denne ene setningen i seg selv vekker mange spennende og rare reaksjoner hos noen mennesker. Her er fem av dem.
When I think back on all the good parts of being a child, few things beat the sensation of sitting on my parents' shoulders. The empowering moment when they lifted me above their heads for me to loom over everyone else. Reaching for my neighbors' apples and being small enough that it was considered charming instead of theft. Those were the days.
Surges are solar ejections that can be as large as the Earth - or even bigger- and relatively cool (in solar standards), which makes them a very interesting topic to study. With the European Solar Telescope we will able to capture the elusive details of the physical processes that lead to surges.
Astrofysisk institutt har et veldig internasjonalt miljø, og har mange samarbeid på tvers av landegrenser. En av fordelene med dette, er at det er store sjanser for å få dra ut på spennende reiser i løpet av mastergraden sin. Selv er jeg masterstudent med på COMAP eksperimentet, som samarbeider med folk fra blant annet USA, England og Canada. Og i februar var jeg så heldig at jeg fikk være med på tur til California!
RoCS hosted the first international workshop on solar imaging with the ALMA observatory, the "new eye" to the Sun. Here the outcome of a week-long brainstorming.
At the Institute of Theoretical Astrophysics the number of researchers is growing tremendously. Get to know five brilliant astrophysicists, their research, ambitions and stories.
As a budding astrophysicist with a self-admitted tendency towards introspection, I often find myself reflecting on the steps I’ve taken to get to this spot in my career, the challenges I’ve faced, and how reality differs so spectacularly from expectation.
In short, and to put it colloquially, life is nonlinear AF.
Space is quite the distance away for us humans on Earth. So naturally, when you tell someone you study astrophysics, they go “that must be awfully theoretical?”. In some cases yes, but it does not have to be.
I’m an Astrophysicist. I’m also a big arthouse cinema enthusiast. This leaves me with the obvious topic to write about: botched science in blockbuster movies.
Let’s begin, shall we?
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.
Coronal rain is one of the most striking features of the solar atmosphere. With the higher resolution of the European Solar Telescope, solar physicists will better understand their structure and formation.
We need the extreme capabilities of the European Solar Telescope in order to fully understand the role of spicules in the mass transport and heating of the outer solar atmosphere.
The Rosseland Centre for Solar physics continues growing and attracting young, talented researchers. Get to know four new PhD students at the beginning of their scientific ventures.
