Gemini Tracks Distant Star Cluster with Adaptive Optics
Gemini Distant Star Cluster Adaptive Optics
<
2017/7/20
We present a proper motion measurement for the halo globular cluster Pyxis, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data as the second, separated by a baseline of ～ 5 yea...
A team of Australian researchers used two Maunakea-based observatories – Gemini North and W. M. Keck Observatory – to discover why some galaxies are clumpy rather than spiral in shape and it appears t...
中国科学院紫金山天文台研究者利用紫金山天文台青海观测站13.7米毫米波射电望远镜对Gemini分子云进行了CO（J=1-0）分子谱线的观测。根据该分子云的部分区域的通道积分图（图1，其中红色的叉表示核候选体的位置）推断分子云核候选体的较大速度差值由像碰撞、紊乱磁场一样的随机过程触发。从线宽的分析（图2）则得到了非热致宽在该分子云中占据主导地位的结论。至于恒星形成，位力质量和LTE质量的关系（图3）...
Stunning exoplanet images and spectra from the first year of science operations with the Gemini Planet Imager (GPI) were featured today in a press conference at the 225th meeting of the American Astro...
A compelling new image from Gemini Observatory peers into the heart of a group of galaxies (VV166) traveling through space together. The variety of galactic forms range from a perfect spiral, to featu...
NOAO/Gemini: Sakurai's Object: Stellar evolution in real time
NOAO/Gemini Sakurai's Object Stellar evolution real time
<
2014/4/16
Stellar lifetimes are measured in billions of years, so changes in their appearance rarely take place on a human timescale. Thus an opportunity to observe a star passing from one stage of life to anot...
Feeding and feedback in the active nucleus of Mrk 1157 probed with Gemini NIFS
galaxies: individual (Mrk 1157) – galaxies: individual (NGC591) – galaxies:Seyfert – galaxies: ISM – infrared: galaxies – galaxies: kinematics and dynamics
<
2011/10/8
We have mapped the stellar and gaseous kinematics, as well as the emission-line flux distributions and ratios, from the inner 450pc radius of Mrk1157, using 2D near-IR spectra obtained with the Gemini...
New Cataclysmic Variable 1RXS J073346.0+261933 in Gemini
stars cataclysmic variables X-ray sources.
<
2011/9/29
In course of the search for the optical identifications associated with ROSAT X-ray sources we have found a highly variable object with the very unusual long-term behavior, color indices and high X-ra...
Gemini GMOS spectroscopy of HeII nebulae in M33
stars atmospheres — stars Wolf-Rayet — ISM HII regions — ISM lines and bands — galaxies individual (M33)—galaxies
<
2010/11/15
We have carried out a narrow-band survey of the Local Group galaxy, M33, in the HeII λ4686 emission line, to identify HeII nebulae in this galaxy. With spectroscopic follow-up observations, we confirm...
Gemini/GMOS Spectroscopy of 26 Strong Lensing Selected Galaxy Cluster Cores
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
<
2011/1/4
We present results from a spectroscopic program targeting 26 strong lensing cluster cores that were visually identified in the Sloan Digital Sky Survey (SDSS) and the Second Red-Sequence Cluster Surve...

Near-IR dust and line emission from the central region of Mrk1066: Constraints from Gemini NIFS
Near-IR dust Gemini NIFS line emission
<
2010/3/8
We present integral field spectroscopy of the inner 350 pc of the Mrk1066 obtained with Gemini NIFS at a spatial resolution of 35 pc. This high spatial resolution allowed us to observe, for the first ...
