Galaxy physical properties from spectral/SED fitting (Telescopes and computers: windows on the early universe)

• Emma CURTIS-LAKE

Room: Zoom Webinar

BAGPIPES tutorial (Software to investigate galaxy evolution)

• Adam CARNALL

Room: Zoom Meeting Room 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](https://drive.google.com/drive/folders/1BZScnYLvdbzHoKOhqRRN_mqv2BNmY2cM)

Cosmological galaxy simulations (Telescopes and computers: windows on the early universe)

• Annalisa PILLEPICH

Room: Zoom Webinar

Illustris-TNG tutorial (Software to investigate galaxy evolution)

• Mohammadreza AYROMLOU (Heidelberg University)

Room: Zoom Webinar 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](https://mybinder.org/v2/gh/jupyterlab/jupyterlab-demo/master?urlpath=lab/tree/demo)).

Galaxy spectra (Telescopes and computers: windows on the early universe)

• Lise CHRISTENSEN

Room: Zoom Webinar

Spectral analysis tools tutorial (Software to investigate galaxy evolution)

• Kasper HEINTZ (University of Iceland)

Room: Zoom Webinar For this tutorial we will use a Jupyter Notebook (stored [here](https://github.com/keheintz/SpecAnalysis)) 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.

Photometry and Photometric redshift (Telescopes and computers: windows on the early universe)

• Gabriel BRAMMER (Cosmic Dawn Center, NBI, KU)

Room: Zoom Webinar

EAZY tutorial (Software to investigate galaxy evolution)

• Clara GIMÉNEZ ARTEAGA
• Katriona GOULD

Room: Zoom Webinar Tutorial on the SED modeling code EAZY (Brammer+2008, ApJ, 686, 1503). GitHub: https://github.com/gbrammer/eazy-py Demo for visualization tool at the very end of this GitHub page. Exercise on Binder: https://mybinder.org/v2/gh/claragimenez/eazy_tutorial/HEAD

Galaxy gas and dust (Telescopes and computers: windows on the early universe)

• Georgios MAGDIS
• Thomas GREVE (UCL)

Room: Zoom Webinar This lecture is divided in two parts: Prof. Magdis will talk about gas content in galaxies and how to measure gas mass. Prof. Greve will discuss modeling of photo-dissociation regions (PDR) and iterstellar medium (ISM) diagnostics.

Present and Future of Interferometry (Telescopes and computers: windows on the early universe)

• Fabian WALTER

Room: Zoom Webinar

Zoom-in Hydrodynamical Simulations (Telescopes and computers: windows on the early universe)

• Freeke VAN DE VOORT

Room: Zoom Webinar

Machine Learning: not all that glitters is gold (Software to investigate galaxy evolution)

• Tom CHARNOCK

Room: Zoom Webinar

Tools for sharing your code and basics of cloud computing (Telescopes and computers: windows on the early universe)

• Iary DAVIDZON (NBI/Cosmic Dawn Center)

Room: Zoom Webinar We will mainly discuss the use of [GitHub](https://github.com/) and [Binder](mybinder.org/) 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.

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

• Liv GISH

Room: Zoom Meeting Room *** 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](https://app.mural.co/signin-join-mural?returnUrl=%2Finvitation%2Fmural%2Fnordicwritingacademy2624%2F1641966483144%3Fsender%3Du5b7a0a44e0d27b37d5644504%26key%3Da4159012-e8f4-4acc-a8b4-41920ad0ac47&title=Value+setting&viral=true)).
