Constraining primordial non-gaussianity by combining next-generation galaxy and 21 cm intensity mapping surveys
(SpringerOpen, 2023)Surveys of the matter distribution contain ‘fossil’ information on possible non-Gaussianity that is generated in the primordialUniverse. This primordial signal survives only on the largest scales where cosmic variance ... -
Constraining the bright-end of the UV luminosity function for z ~ 7-9 galaxies: results from CANDELS/GOODS-South
(OUP, 2013)The recent Hubble Space Telescope near-infrared imaging with the Wide-Field Camera #3 (WFC3) of the GOODS-South field in the CANDELS program covering nearly 100 arcmin2, along with already existing Advanced Camera for ... -
Cosmos2020: A panchromatic view of the universe to z∼10 from two complementary catalogs
(IOP Publishing, 2022)The Cosmic Evolution Survey (COSMOS) has become a cornerstone of extragalactic astronomy. Since the last public catalog in 2015, a wealth of new imaging and spectroscopic data have been collected in the COSMOS field. This ... -
Extremely broad lyαline emission from the molecular intragroup medium in Stephan’s quintet: evidence for a turbulent cascade in a highly clumpy multiphase medium?
(IOP Publishing, 2022)We present Hubble Space Telescope Cosmic Origin Spectrograph (COS) UV line spectroscopy and integral-field unit (IFU) observations of the intragroup medium in Stephan’s Quintet (SQ). SQ hosts a 30 kpc long shocked ... -
Interferometric H I intensity mapping: perturbation theory predictions and foreground removal effects
(Oxford University Press, 2023)We provide perturbation theory predictions for the H I intensity mapping power spectrum multipoles using the Effective Field Theory of Large Scale Structure, which should allow us to exploit mildly non-linear scales. ... -
Mightee-hi: Evolution of hi scaling relations of star-forming galaxies at z < 0.5*
(IOP Publishing, 2022)We present the first measurements of H I galaxy scaling relations from a blind survey at z > 0.15. We perform spectral stacking of 9023 spectra of star-forming galaxies undetected in H I at 0.23 < z < 0.49, extracted ... -
Multi-wavelength properties of radio- and machine-learning-identified counterparts to submillimeter sources in s2cosmos
(The Astrophysical Journal, 2019)We identify multi-wavelength counterparts to 1147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio+machine-learning method trained on a large sample of ... -
The physical properties of star-forming galaxies with strong [oiii]lines at z=3.25
(IOP Publishing, 2022)We present an analysis of physical properties of 34 [O III] emission-line galaxies (ELGs) at z = 3.254 ± 0.029 in the Extended Chandra Deep Field South (ECDFS). These ELGs are selected from deep narrow H2S(1) and broad Ks ... -
Redshift evolution of galaxy group X-ray properties in the SIMBA simulations
(Oxford University Press, 2023)We examine the evolution of intragroup gas rest-frame X-ray scaling relations for group-sized haloes (M500 = 1012.3–1015 M) in the SIMBA galaxy formation simulation. X-ray luminosity LX versus M500 shows increasing deviation ... -
The VLA-COSMOS 3 GHz Large Project: Evolution of specific star formation rates out to z∼5
(IOP Publishing, 2020)We provide a coherent, uniform measurement of the evolution of the logarithmic star formation rate (SFR) – stellar mass (M∗) relation, called the main sequence of star-forming galaxies (MS), for starforming and all galaxies ...
