Anchoring the distance scale via X-ray/infrared data for Cepheid clusters: SU Cas

Gallo, Luigi C.; Turner, David Gerald, 1945-; Majaess, Daniel J.; Lane, D. J.; Gieren, W.; Bonatto, C.; Balam, D.; Berdnikov, L. (American Astronomical SocietyIOP Publishing, 2012-07-10)

New X-ray (XMM-Newton) and JHK[subscript s] (Observatoire du Mont-Megantic) observations for members of the star cluster Alessi 95, which Turner et al. discovered hosts the classical Cepheid SU Cas, were used in tandem ...
A cluster of class I/f/II young stellar objects discovered near the Cepheid SU Cas

Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W. (Oxford Academic, 2012-04)

Preliminary constraints are placed on a cluster of young stellar objects (J2000 02:54:31.4 +69:20:32.5) discovered in the field of the classical Cepheid SU Cas. The Wide-field Infrared Survey Explorer (WISE) 3.4-, 4.6-, ...
High-velocity-dispersion cold gas in ULIRG Outflows – I. Direct simulations

Williamson, David John; Thacker, Robert John, 1970-; Scannapieco, E.; Bruggen, M. (Oxford University Press, 2014-06)

Observations (e.g. Phillips, Heckman et al., Martin) have revealed cold gas with large velocity dispersions (≈300 km s⁻¹) within the hot outflows of ultraluminous infrared galaxies (ULIRGs). This gas ...
Massive open star clusters using the VVV survey I. Presentation of the data and description of the approach

Majaess, Daniel J.; Chene, A.-N.; Borissova, J.; Clarke, J. R. A.; Bonatto, C.; Bidin, C. Moni; Sale, S. E.; Mauro, F.; Kurtev, R.; Baume, G. (EDP Sciences for European Southern Observatory, 2012-09)

Context. The ESO Public Survey “VISTA Variables in the Vía Láctea” (VVV) provides deep multi-epoch infrared observations for unprecedented 562 sq. degrees of the Galactic bulge, and adjacent regions of the disk. Aims. The ...
New evidence supporting membership for TW Nor In Lyngå 6 and the Centaurus spiral arm

Majaess, Daniel J.; Turner, David Gerald, 1945-; Moni Bidin, Christian; Mauro, Francesco; Geisler, Douglas; Gieren, Wolfgang; Minniti, Dante; Chene, Andre-Nicolas; Lucas, Philip; Borissova, Jura (IOP Publishing, 2011-11-10)

The putative association between the 10.^d 8 classical Cepheid TW Nor and the open cluster Lyngå 6 has generated considerable debate in the literature. New JHK_s photometry in tandem with existing ...
New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge

Majaess, Daniel J.; Borissova, J.; Chene, A.-N.; Ramirez Alegria, S.; Sharma, S.; Clarke, J. R. A.; Kurtev, R.; Negueruela, I.; Marco, A.; Amigo, P. (EDP Sciences, 2014)

Context. VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Milky Way bulge and an adjacent ...
On the form of the Spitzer Leavitt Law and its dependence on metallicity

Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W. (American Astronomical Society, 2013-08-01)

The form and metallicity dependence of Spitzer mid-infrared Cepheid relations are a source of debate. Consequently, Spitzer 3.6 and 4.5 [mu]m period–magnitude and period–color diagrams were re-examined via robust routines, ...
VVV DR1: the first data release of the Milky Way bulge and southern plane from the near-infrared ESO public survey VISTA variables in the Vía Láctea

Majaess, Daniel J.; Saito, R. K.; Hempel, M.; Minniti, D.; Lucas, P. W.; Rejkuba, M.; Toledo, I.; Gonzalez, O. A.; Alonso-Garcia, J.; Irwin, M. J. (EDP Sciences for European Southern Observatory, 2012-01)

Context. The ESO public survey VISTA variables in the Vía Láctea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for about five years. Aims. We ...
