Multiple Emission Lines of Hα Emitters at z ∼ 2.3 from the Broad- and Medium-band Photometry in the ZFOURGE Survey

Autor: Nuo Chen, Kentaro Motohara, Lee Spitler, Kimihiko Nakajima, Rieko Momose, Tadayuki Kodama, Masahiro Konishi, Hidenori Takahashi, Kosuke Kushibiki, Yukihiro Kono, Yasunori Terao

Publikováno v: The Astrophysical Journal, Vol 964, Iss 1, p 5 (2024)

We present a multiple emission line study of ∼1300 H α emitters (HAEs) at z ∼ 2.3 in the ZFOURGE survey. In contrast to the traditional spectroscopic method, our sample is selected based on the flux excess in the ZFOURGE K _s broadband data rela

The discovery in deep near-infrared surveys of a population of massive quiescent galaxies at $z>3$ has given rise to the question of how they came to be quenched so early in the history of the Universe. Measuring their molecular gas properties can di

Cronomoons: origin, dynamics, and light-curve features of ringed exomoons

Autor: Mario Sucerquia, Jaime A Alvarado-Montes, Amelia Bayo, Jorge Cuadra, Nicolás Cuello, Cristian A Giuppone, Matías Montesinos, J Olofsson, Christian Schwab, Lee Spitler, Jorge I Zuluaga

In recent years, technical and theoretical work to detect moons and rings around exoplanets has been attempted. The small mass/size ratios between moons and planets means this is very challenging, having only one exoplanetary system where spotting an

Lyman Continuum Galaxy Candidates in COSMOS

Publikováno v: The Astrophysical Journal. 924:14

Star-forming galaxies are the sources likely to have reionized the universe. As we cannot observe them directly due to the opacity of the intergalactic medium at $z\gtrsim5$, we study $z\sim3\text{--}5$ galaxies as proxies to place observational cons

Probing the 2-D Kinematic Structure of Early-Type Galaxies Out to 3 Effective Radii

Autor: Robert N. Proctor, Duncan A. Forbes, Aaron J. Romanowsky, Jean P. Brodie, Jay Strader, Max Spolaor, J. Trevor Mendel, Lee Spitler, Victor P. Debattista, C. C. Popescu

Publikováno v: AIP Conference Proceedings.

We detail an innovative new technique for measuring the 2-D velocity moments (rotation velocity, velocity dispersion and Gauss-Hermite coefficients h$_3$ and h$_4$) of the stellar populations of galaxy halos using spectra from Keck DEIMOS multi-objec
