“…The telescope undertook a series of sky surveys including the 3π Survey, covering 30 000 deg 2 north of δ = −30 • with two pairs of observations per year in each of five filters. These filters (g P1 , r P1 , i P1 , z P1 and y P1 ; Tonry et al 2012) extend further into the red optical than SDSS, making Pan-STARRS 1 appealing for studying late-type objects in the solar neighbourhood (Deacon et al 2011;Liu et al 2011Liu et al , 2013Best et al 2013Best et al , 2015. This combination of properties has already resulted in the identification of the largest number of ultracool companions to date, with a near-doubling of the late-M and L dwarf wide separation (>100 au) companion populations (Deacon et al 2014) as well as the discovery of two T dwarf companions (Deacon et al 2012a,b).…”

We present the discovery of a 360 AU separation T3 companion to the tight (3.1 AU) M4.5+M6.5 binary 2MASS J02132062+3648506. This companion was identified using Pan-STARRS 1 data and, despite its relative proximity to the Sun (22.2 +6.4 −4.0 pc; Pan-STARRS 1 parallax) and brightness (J=15.3), appears to have been missed by previous studies due to its position near a diffraction spike in 2MASS. The close M dwarf binary has active X-ray and Hα emission and shows evidence for UV flares. The binary's weak GALEX UV emission and strong Na I 8200 Å Na absorption leads us to an age range of ∼1-10 Gyr. Applying this age range to evolutionary models implies the wide companion has a mass of 0.063±0.009 M ⊙ . 2MASS J02132+3648 C provides a relatively old benchmark close to the L/T transition and acts as a key, older comparison to the much younger early-T companions HN Peg B and GU Psc b.

“…Because no y -band observation is available in the SDSS, the translation equation and parameters provided by Tonry et al (2012) were used to obtain the y -band magnitudes of the stars. Tonry et al (2012) derived a relation between the z -band of the SDSS and the y -band of the PS1 for stellar objects.…”

Aims. We studied the r -, z -, and y -band images of merging galaxies from the observations of the Panoramic Survey Telescope & Rapid Response System (Pan-STARRS). The merging galaxies were selected from our merging catalog that was created by checking the images of the Red-Sequence Cluster Survey 2 from the observations of the Canada France Hawaii Telescope. Methods. By using the homomorphic-aperture, we determined the photometric results of these merging systems. To obtain accurate photometry, we calibrated the Pan-STARRS r -, z -, and y -band data to match the results of Sloan Digital Sky Survey Data Release 9. We also investigated the stellar masses of the merging galaxies by comparing the Wide-field Infrared Survey Explorer 3.4 µm emission with the calibrated y -band data.Results. We present a catalog of the r -, z -, and y -band photometric results for 4698 merging galaxies. For extended sources, our results suggest that the homomorphic-aperture method can obtain more reasonable results than the Desktop Virtual Observatory photometry. We derived new relations between the Pan-STARRS y -band luminosities and the stellar masses of the merging galaxies. Our results show that the stellar masses of the merging galaxies range from 10 8 to 10 13 M ; some of the dry mergers could be as massive as 10 13 M .

Digital Sky Surveys from the Ground: Status and Perspectives

I first review the status of Digital Sky Surveys. The focus will be on extragalactic surveys with an area of more than 100deg 2 . The Sloan Digital Sky Survey is the archetype of such imaging surveys and it is its great success that has prompted great activity in this field. The latest surveys explore wider, fainter and higher resolution and also a longer wavelength range than SDSS. Many of these surveys overlap particularly in the S Hemisphere where we now have Pan-STARRS, DES and the ESO VST surveys, and our aim here is to compare their properties. Since there is no dedicated article on the VST ATLAS in this symposium, we shall especially review the properties of this particular survey. This easily fits onto our other main focus which is to compare overlapping Southern Surveys and see how they best fit with the available NIR imaging data. We conclude that the Southern Hemisphere will soon overtake the North in terms of multiwavelength imaging. However, we note that the South has more limited opportunities for spectroscopic follow-up and this weakness will persist during the LSST era. Some new perspectives are offered on this and other aspects of survey astronomy.
