ABSTRACT We present the COSMOS2015 24 catalog, which contains precise photometric redshifts and stellar masses for more than half a million objects over 2deg 2 COSMOS field. Including new <?CDATA ${{YJHK}}_{{\rm{s}}}$?> images from UltraVISTA-DR2 survey, Y-band Subaru/Hyper-Suprime-Cam, infrared data Spitzer Large Area Survey with Hyper-Suprime-Cam legacy program, this near-infrared-selected catalog is highly optimized study of galaxy evolution environments in early universe. To maximize...
Abstract We report the discovery and monitoring of near-infrared counterpart (AT2017gfo) a binary neutron-star merger event detected as gravitational wave source by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo (GW170817) short gamma-ray burst Fermi Gamma-ray Burst Monitor (GBM) Integral SPI-ACS (GRB 170817A). The evolution transient light is consistent with predictions for behavior “kilonova/macronova” powered radioactive decay massive neutron-rich nuclides...
We present measurements of the stellar mass functions (SMFs) star-forming and quiescent galaxies to z = 4 using a sample 95,675 Ks-selected in COSMOS/UltraVISTA field. The SMFs combined population are good agreement with previous show that density universe was only 50%, 10%, 1% its current value at ∼ 0.75, 2.0, 3.5, respectively. drives most overall growth, these increasing as ρstar∝(1 + z)−4.7 ± 0.4 since whereas increases z)−2.3 0.2. At > 2.5, dominate total SMF all masses, although...
In this paper we describe the first data release of UltraVISTA near-infrared imaging survey COSMOS field. We summarise key goals and design provide a detailed description our reduction techniques. stacked, sky-subtracted images in YJHKs narrow-band filters constructed from collected during year observations. Our stacked reach 5σAB depths an aperture 2″ diameter ~25 Y ~24 JHKs bands all have sub-arcsecond seeing. To 5σ limit, Ks catalogue contains 216 268 sources. carry out series quality...
Gamma-ray bursts (GRBs) serve as powerful probes of the early Universe, with their luminous afterglows revealing locations and physical properties star forming galaxies at highest redshifts, potentially locating first generation (Population III) stars. Since GRB have intrinsically very simple spectra, they allow robust redshifts from low signal to noise spectroscopy, or photometry. Here we present a photometric redshift z~9.4 for Swift-detected 090429B based on deep observations...
We report extensive observational data for five of the lowest redshift Super-Luminous Type Ic Supernovae (SL-SNe Ic) discovered to date, namely PTF10hgi, SN2011ke, PTF11rks, SN2011kf and SN2012il. Photometric imaging transients at +50 +230 days after peak combined with host galaxy subtraction reveals a luminous tail phase four these SL-SNe. A high resolution, optical near infrared spectrum from xshooter provides detection broad He I $\lambda$10830 emission line in (+50d) SN2012il, revealing...
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in Universe, studying sources these energetic photons has been a major driver astronomy for past 50 years. Here we present multiwavelength observations unique selected transient, discovered by Swift, which was accompanied bright across electromagnetic spectrum, whose properties are unlike any previously observed source. We pinpoint event to center small, star-forming galaxy at redshift z=0.3534....
We have gathered optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for total 76 GRBs, and present an additional three pre-Swift not included in earlier sample. Furthermore, we publish 840 new points 42 GRB afterglows, sets 050319, 050408, 050802, 050820A, 050922C, 060418, 080413A 080810. analyzed light curves all derived spectral energy distributions with best quality, allowing us estimate host...
(Abridged). We present a sample of 77 optical afterglows (OAs) Swift detected GRBs for which spectroscopic follow-up observations have been secured. provide linelists and equivalent widths all lines redward Ly-alpha. discuss to what extent the current bursts with OA spectroscopy is biased subsample GRBs. For that purpose we define an X-ray selected optimal conditions ground-based follow up from period March 2005 September 2008; 146 fulfill our criteria. derive redshift distribution this...
Abstract The Cosmic Evolution Survey (COSMOS) has become a cornerstone of extragalactic astronomy. Since the last public catalog in 2015, wealth new imaging and spectroscopic data have been collected COSMOS field. This paper describes collection, processing, analysis these to produce reference photometric redshift catalog. Source detection multiwavelength photometry are performed for 1.7 million sources across 2 deg field, ∼966,000 which measured with all available broadband using both...
We present a catalog covering 1.62 deg2 of the COSMOS/UltraVISTA field with point-spread function (PSF) matched photometry in 30 photometric bands. The covers wavelength range 0.15–24 μm including available GALEX, Subaru, Canada–France–Hawaii Telescope, VISTA, and Spitzer data. Catalog sources have been selected from DR1 UltraVISTA Ks band imaging that reaches depth Ks, tot = 23.4 AB (90% completeness). PSF-matched is generated using position-dependent PSFs ensuring accurate colors across...

The mergers of binary compact objects such as neutron stars and black holes are central interest to several areas astrophysics, including the progenitors gamma-ray bursts (GRBs), sources high-frequency gravitational waves likely production sites for heavy element nucleosynthesis via rapid capture (the r-process). These elements include some great geophysical, biological cultural importance, thorium, iodine gold. Here we present observations exceptionally bright burst GRB 230307A. We show...
