DAWN Winter School

7 Feb 2022, 08:00 → 11 Feb 2022, 16:05 Europe/Copenhagen

Zoom Webinar (online)

Francesco VALENTINO (Niels Bohr Institute - University of Copenhagen), Iary DAVIDZON (NBI/Cosmic Dawn Center)

Astrophysics still requires a large amount of practical knowledge in order to carry out compelling research, either from an observational or theoretical  perspective. There are many cutting-edge concepts and "tricks of the trade" that are often overlooked in university classes, despite being crucial to perform (or at least have a critical understanding of) state-of-the-art studies. For example: How galaxy properties are measured nowadays? And how to judge the reliability of the estimates in a certain paper? What are the caveats one should be aware of, before using the results of a cosmological simulation? And how to download the right information from the data base?

Besides that, there are fundamental soft skills to write convincing proposals, increase the impact of a paper, make a code easily re-usable by other scientists... Despite their importance, most of the students acquire these skills rather casually, e.g. from internet websites or during informal conversations with colleagues. 

The DAWN Winter School aims at addressing these "off-the-textbook" topics in a structured way, making the students' learning curve less steep. Being conceived for astrophysicists at the very beginning of their journey, it will also be the occasion to discuss promising research perspectives with the next-generation facilities, along with potential career developments. 

Since this event is organized by the Cosmic DAWN Center, emphasis will be placed on topics related to galaxy formation and evolution in the early universe. However, students from any discipline may attend the last two days, which will be dedicated to the soft skill that are useful also outside Astrophysics. See the scheduled lectures and hands-on tutorials will be available at this link.

The activities have been originally conceived for students in their last year of MSc and those who just enrolled in a PhD programme. Nonetheless, more senior students and researchers are also very welcome to join! More details can be found in the Scientific and Didactic Rationale.

The Winter School will be fully online, from February 7th to 11th, 2022. There is no limitation to the number of slots for virtual participation. In the FAQ page you will find the latest updates regarding Zoom attendance and other issues.

09:00 Webinar open for connection

From this time on, you can connect to the Zoom Webinar.
If you successfully registered but haven't received the instruction to connect, please send us an email.

1 Welcome speech

The organizers will introduce the Cosmic Dawn Center and also provide some information about the virtual infrastructure and the guidelines of this event.

Speakers: Allan HORNSTRUP, Francesco VALENTINO (Niels Bohr Institute - University of Copenhagen)

2 Galaxy physical properties from spectral/SED fitting

Speaker: Emma CURTIS-LAKE

3 BAGPIPES tutorial

This will be hosted on a Zoom Meeting Room. Link and passcode will be provided on the Webinar (for which you already registered) and via email.

For this tutorial we will use Google Colab

Before the beginning
connect to this link

Speaker: Adam CARNALL

4 Cosmological galaxy simulations

Speaker: Annalisa PILLEPICH

5 Illustris-TNG tutorial

For this tutorial we will use TNG JupyterLab. Since it may take some time to set up your TNG account we strongly recommend to take the following actions at least 5 days before the Winter School starts.

Analyzing a large cosmological simulation like Illustris-TNG is often very expensive in terms of memory storage and computational power. Given the large number of students attending our Winter School, there is the possibility that this tutorial may overload the JupyterLab system. If this happens, we will modify/replace part of the "live demo" e.g. asking the participants not to engage the system all at the same time.

Your to-do list before the beginning

1. register at https://www.tng-project.org/users/register/, being sure to use the same email address you used to register to the Winter School, and write "DAWN Winter School" in the Location box.

2. request access to https://www.tng-project.org/data/lab/ with the TNG credentials created in step 1.

3. [optional] after your request is approved, you can log in and launch the TNG JupyterLab (e.g., you can have a look to this quick demo).

Speaker: Mohammadreza AYROMLOU (Heidelberg University)

6 Galaxy spectra

Speaker: Lise CHRISTENSEN

7 Spectral analysis tools tutorial

For this tutorial we will use a Jupyter Notebook (stored here) that will run fully online via Binder. However, there is an extra exercise that anyone can download and run on their computer. See instructions below.

Your to-do list before the beginning

Main exercise

1. Click on the following link to load the Notebook on your browser: https://mybinder.org/v2/gh/keheintz/SpecAnalysis/HEAD?labpath=DWS20222_specutils.ipynb. It may take a few minutes to start.
2. Once the JupyterLab page is up and running, you can use the Notebook without installing software or libraries locally.

Extra exercise (not mandatory)

1. Open a Terminal on your computer
2. Download the repository with the command git clone https://github.com/keheintz/SpecAnalysis.git
3. Enter the directory: cd SpecAnalysis
4. Install the required package: pip install VoigtFit
5. Launch the interactive Python script: python VoigtFit_example.py
6. Follow the instructions on the interactive window. If the window doesn't pop up, we'll provide assistance during the tutorial to solve the problem.

Speaker: Kasper HEINTZ (University of Iceland)

14 Tools for sharing your code and basics of cloud computing

We will mainly discuss the use of GitHub and Binder to make software more accessible to the astro-community (and beyond).
We might try an interactive example of multi-user code development (repository "fork" and "push request"). In that case, it would be helpful (but not mandatory) if you have a GitHub account already in place.

Speaker: Iary DAVIDZON (NBI/Cosmic Dawn Center)

18 Cope with stress, and work-life balance during a PhD

*** A dedicated Zoom link for this session has been circulated via email ***

Stress has become part of most students’ academic life. Research shows that approximately one third of PhD students sometimes feel worn out and that their work takes up so much time and energy that it affects their private life. But it does not have to be like that!

By attending the workshop, you will become aware of your own indicators and causes of stress, and gain insights to how to build a repertoire of stress prevention strategies to obtain a batter work-life balance.

After attending the workshop, you can:
 Identify your own stress indicators and know when to act on them
 Be aware of the causes of stress
 Build a repertoire of stress preventions strategies
 Identify your life values and plan accordingly to embrace a work-life balance

These 3 hours include work in groups (Zoom breakout rooms) and active feedback from the audience. Sensitive/personal matters may be discussed, therefore this seminar will not be recorded.

To gain the best experience of the workshop we recommend that you join from a computer or device on which you can download (and use) the material below, and interact on the Mural website (join Mural from this link).
