Autor: Luka Vujeva, Charles L. Steinhardt, Christian Kragh Jespersen, Brenda L. Frye, Anton M. Koekemoer, Priyamvada Natarajan, Andreas L. Faisst, Pascale Hibon, Lukas J. Furtak, Hakim Atek, Renyue Cen, Albert Sneppen
Publikováno v: The Astrophysical Journal, Vol 974, Iss 1, p 23 (2024)
Several large JWST blank field observing programs have not yet discovered the first galaxies expected to form at 15 ≤ z ≤ 20. This has motivated the search for more effective survey strategies that will be able to effectively probe this redshift

The HR 2562 system is a rare case where a brown dwarf companion resides in a cleared inner hole of a debris disk, offering invaluable opportunities to study the dynamical interaction between a substellar companion and a dusty disk. We present the fir

Protoclusters, the progenitors of the most massive structures in the Universe, have been identified at redshifts of up to 6.6. Besides exploring early structure formation, searching for protoclusters at even higher redshifts is particularly useful to

Giant star-forming regions (clumps) are widespread features of galaxies at $z \approx 1-4$. Theory predicts that they can play a crucial role in galaxy evolution if they survive to stellar feedback for > 50 Myr. Numerical simulations show that clumps
